Introduction : Near field communication (NFC) is a set of standards for smartphones and similar devices to establish radio communication with each other by touching them together or bringing them into close proximity, usually no more than a few centimetres. Present and anticipated applications include contactless transactions, data exchange, and simplified setup of more complex communications such as Wi-Fi. Communication is also possible between an NFC device and an unpowered NFC chip, called a "tag". NFC standards cover communications protocols and data exchange formats, and are based on existing radio-frequency identification (RFID) standards including ISO/IEC 14443 and FeliCa. The standards include ISO/IEC 18092 and those defined by the NFC Forum, which was founded in 2004 by Nokia, Philips and Sony, and now has more than 160 members. The Forum also promotes NFC and certifies device compliance. Features : CCID Standard PCSC Compliant Read / Write Speed up to 424kbps ISO/IEC 18092 (NFC) and FeliCa Tag Support ISO14443 Type A and B and MiFare card support Bi-Color LED Compact size : 98mm (L) x 65mm (W) x 12.8mm (H) Light Weight : 70g CE, FCC and RoHS compliant User Controllable Buzzer (optional) Advantages of Near Field Communication : Knowing what near field communication is and how it works is one thing, but while it may seem like a novel idea in theory, how exactly will it benefit you? If you̢۪re considering upgrading to a NFC enabled smartphone, already own one but have never used the technology, or are simply curious to learn more about its advantages, read on to find out why NFC technology is gaining in popularity. Ease of Use : By far the most obvious benefit of near field communication and the contactless payment systems it creates is its ease of use. No need to carry multiple credit cards or dig through your wallet for the right one. No more lost movie tickets or subway passes. And finally, no more individual rewards cards from different stores to track. Instead of carrying a card for every store you shop at, load them on your phone and coupons and rewards points go straight to your account without ever digging out the card. Security : If your wallet is stolen, a thief has instant access to all your credit cards, debit cards, and photo IDs. Storing this information all in one place on your smartphone may sound dangerous at first, but actually provides a safer environment than your physical wallet. While you can̢۪t password protect your wallet, you can password protect your smartphone. No thief can use your cards if they can̢۪t unlock the phone to get at them. In addition, near field communication often creates a secure channel for communication and uses data encryption when sending sensitive information between your phone and another device, such as a card reader. This prevents hackers from stealing that info. Finally, having your information stored on one device cuts down on your risk of losing or misplacing a credit card when you̢۪re trying to juggle three or more cards in your wallet and switching between them for different purchases. Thieves will find your smartphone a lot harder to swipe then that wallet in your back pocket, and if worse comes to worse a GPS enabled smartphone can be tracked down and recovered. Versatility : Perhaps one of the most important aspects of near field communication technology is its versatility. Ease of use is important to convince individuals to stick with the technology, but it needs to cover a variety of uses for others to really catch NFC fever. Customers can check out at a store, purchase and load concert tickets to their smartphones, board the subway, read information from a smart poster, and many other tasks all from a single device. Many individuals carry a smartphone already and with the power near field communication brings to it, those individuals can have everything they need at the tip of their fingers without lugging around ticket stubs or parking passes. The technology can even connect with friends to share information, play games, and transfer data. NFC strives to embrace both work and play, a crucial factor in creating its success. No interference due to decaying fields Allows communication both between two powered and passive devices Convenient usage by simply holding the two devices close to each other Typical Applications : eCommerce : NFC devices can be used in contactless payment systems, similar to those currently used in credit cards and electronic ticket smartcards, and allow mobile payment to replace or supplement these systems. For example, Google Wallet allows consumers to store credit card and store loyalty card information in a virtual wallet and then use an NFC-enabled device at terminals that also accept MasterCard PayPass transactions.Germany, Austria, Finland, New Zealand, and Italy have trialed NFC ticketing systems for public transport, while China has brought it into service on buses GLoss the country. India is implementing NFC based transactions in box offices for ticketing purposes. Social networking : NFC can be used in social networking situations, such as sharing contacts, photos, videos or files, and entering multiplayer mobile games. The NFC Forum promotes the potential for NFC-enabled devices to act as electronic identity documents and keycards. As NFC has a short range and supports encryption, it may be more suitable than earlier, less private RFID systems. Bluetooth and Wi-Fi connections : NFC offers a low-speed connection with extremely simple setup, and can be used to bootstrap more capable wireless connections. For example, the Android Beam software uses NFC to automatically complete the steps of enabling, pairing and establishing a Bluetooth connection when doing a file transfer.Nokia has used NFC technology to pair Bluetooth headsets and speakers with one tap in its NFC-enabled devices. The same principle can be applied to the configuration of Wi-Fi networks. Network access control Micro-payment NFC mobile tag Public Transportation Terminals Automatic Fare Collection Physical access control Customer Loyalty Time attendance Contactless public phones Vending machines Conclusion : Providing secure channel will avoid the draw backs such as evesdropping or data modification. NFC is compatible with existing RFID infrastructures. NFC is an efficient technology for communications with short ranges

We are a well-known Manufacturer, Exporter & Supplier of AC Current Sensor . The Hall Effect is an ideal sensing technology. The Hall element is constructed from a thin sheet of conductive material with output connections perpendicular to the direction of current flow. When subjected to a magnetic field, it responds with an output voltage proportional to the magnetic field strength. The voltage output is very small (µV) and requires additional electronics to achieve useful voltage levels. When the Hall element is combined with the associated electronics, it forms a Hall Effect sensor. The heart of every MICRO SWITCH Hall effect device is the integrated circuit chip that contains the Hall element and the signal conditioning electronics. The XYZ consists of a precise, low-temperature drift linear hall Sensor IC with temperature compensation circuit and a current transformer with 0.24 Ohm typical internal conductor resistance. This extremely low resistance can effectively reduce power loss, operating temperature and increase the reliability greatly. Applied current flowing through this conduction path generates a magnetic field which I s sensed by the integrated Hall IC and converted into a proportional voltage. Working Principle : Theory of the Hall Effect : When a current-carrying conductor is placed into a magnetic field, a voltage will be generated perpendicular to both the current and the field. This principle is known as the Hall Effect. Figure 2-1 illustrates the basic principle of the Hall Effect. It shows a thin sheet of semiconducting material (Hall element) through which a current is passed. The output connections are Perpendicular to the direction of current. When no magnetic field is present (Figure 2-1), current distribution is uniform and no potential difference is seen across the output. When a perpendicular magnetic field is present, as shown in Figure 2-2, a Lorentz force is exerted on the current. This force disturbs the current distribution, resulting in a potential difference (voltage) across the output. This voltage is the Hall voltage (VH). The interaction of the magnetic field and the current is shown in equation form as equation 2.1. Advantages : Very economical Can measure both DC and AC current Current sensing is easy Applications : Current sensing Power sensing Proximity detection Speed detection

Adjustable Buffer- a potentiometer can be added to the circuit to adjust the sensitivity range Variable Deflection Threshold Switch- an op amp is used and outputs either high or low depending on the voltage of the inverting input. In this way you can use the flex sensor as a switch without going through a microcontroller Resistance to Voltage Converter - use the sensor as the input of a resistance to voltage converter using a dual sided supply op-amp. A negative reference voltage will give a positive output. Should be used in situations when you want output at a low degree of bending Mechanical Specifications : Life Cycle : >1 million Height : 0.43mm (0.017") Temperature Range : -35 o C to +80 o C Electrical Specifications : Flat Resistance : 25K Ohms Resistance Tolerance : ±30% Bend Resistance Range : 45K to 125K Ohms (depending on bend radius) Power Rating : 0.50 Watts continuous. 1 Watt Features : Angle Displacement Measurement Bends and Flexes physically with motion device Possible Uses Robotics Gaming (Virtual Motion) Medical Devices Computer Peripherals Musical Instruments Physical Therapy Simple Construction Low Profile

We are one of the leading Manufacturers, Exporters & Suppliers of Tilt Sensor . The Tilt Sensor operates on 5V dc supply. It gives 3 output voltages corresponding to 3 axis movement of sensor. The Tilt Sensor is widely used for monitoring the boom angle of cranes and material handlers, indicating pitch and roll of vehicles sail boats, and aircraft, etc. We supply excellently performing and durable Tilt Sensor at competitive prices. Working Principle : The ADXL335 is a complete 3-axis acceleration measurement system. The ADXL335 has a measurement range of ±3 g minimum. It contains a polysilicon surface-micro machined sensor and signal conditioning circuitry to implement open-loop acceleration measurement architecture. The output signals are analog voltages that are proportional to acceleration. The accelerometer can measure the static acceleration of gravity in tilt-sensing applications as well as dynamic acceleration resulting from motion, shock, or vibration. The sensor is a polysilicon surface-micro machined structure built on top of a silicon wafer. Polysilicon springs suspend the structure over the surface of the wafer and provide a resistance against acceleration forces. Deflection of the structure is measured using a differential capacitor that consists of independent fixed plates and plates attached to the moving mass. The fixed plates are driven by 180 o out-of-phase square waves. Acceleration deflects the moving mass and unbalances the differential capacitor resulting in a sensor output whose amplitude is proportional to acceleration. Phase-sensitive demodulation techniques are then used to determine the magnitude and direction of the acceleration. Applications : Indicating pitch and roll of vehicles sail boats, and aircraft Monitoring the boom angle of cranes and material handlers Measuring the "look angle" of a satellite antenna towards a satellite In the field of robotics or fall detection

We are one of the leading Manufacturers, Exporters & Suppliers of Thermal Printer . The Thermal Printer we offer is a plug and play, compact, light weight printer which works on thermal printing technology. The Thermal Printer communicates on RS232 protocol. The Thermal Printer has 2 Inch paper width, 3v to 6.6v operation, easy loading paper. This Thermal Printer comes with a printing speed up to 70mm/s. Introduction : Thermal printing (or direct thermal printing) is a digital printing process which produces a printed image by selectively heating coated thermochromic paper, or thermal paper as it is commonly known, when the paper passes over the thermal print head. The coating turns black in the areas where it is heated, producing an image. Two-color direct thermal printers can print both black and an additional color (often red) by applying heat at two different temperatures. Thermal transfer printing is a related method that uses a heat-sensitive ribbon instead of heat-sensitive paper. A printer that uses heat to transfer an impression onto paper is called Thermal Printer. There are two kinds of Thermal Printers : Thermal wax transfer : a printer that adheres a wax-based ink onto paper. A thermal printhead melts wax-based ink from the transfer ribbon onto the paper. When cool, the wax is permanent. This type of thermal printer uses an equivalent panel of ink for each page to be printed, no matter if a full page or only one line of print is transferred. Monochrome printers have a black page for each page to be printed, while color printers have either three (CMY) or four (CMYK) colored panels for each page. Unlike thermal dye transfer printers, also called dye sublimation printers, these printers print images as dots, which means that images must be dithered first. As a result, images are not quite photo-realistic, although they are very good. The big advantages of these printers over thermal dye transfer printers are that they don't require special paper and they are faster. Direct thermal : a printer that prints the image by burning dots onto coated paper when the paper passes over a line of heating elements. Early fax machines used direct thermal printing. Printer Mechanism with Controller Board : This option includes the same mechanism described above, paired with a fully populated controller board, including CPU. For mechanism-based designs, the application or overall mechanical design may dictate whether a straight or curved paper path is required. For example, a straight path is generally necessary to accommodate peel-off label stock (see Figure 1). Features : Printer Type : Thermal Direct Printer Resolution : 8 Dots/mm Paper width : 58 mm Paper roll diameter : Length max. 30 mm - 10 Meter Printing Width : 48 mm Printing speed max 70 mm/sec.
