Leading Manufacturer, Supplier & Retailer of DHT11 Digital Temperature Sensor, VIBRATION SENSOR MODULE, Bmp180 Digital Barometric Pressure Sensor, MQ-2 Smoke sensor and Soil Moisture Sensor.
The DHT11 sensor is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is: you can only get new data from it once every 2 seconds, so when using our library, sensor readings can be up to 2 seconds old.
Measuring the absolute pressure of the environment using a digital barometer such as this has some interesting applications. By converting the pressure measured into altitude, you have a reliable sensor for determining the height of your robot, plane or projectile! Using a sensor as capable as the BMP180 you can achieve accuracy of 1m, with noise of only 17cm in ultra high resolution noise. The device will operate at only 0.3uA meaning low current draw for battery powered applications.
Sensitive material of MQ-2 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exist, The sensor's conductivity is more higher along with the gas concentration rising. Please use simple electrocircuit, Convert change of conductivity to correspond output signal of gas concentration. MQ-2 gas sensor has high sensitivity to LPG, Propane and Hydrogen, also could be used to Methane and other combustible steam, it is with low cost and suitable for different application.
This is a simple water sensor, can be used to detect soil moisture Module Output is high level when the soil moisture deficit, or output is low Can be used in module plant waterer device, and the plants in your garden no need people to manage
The sensor provides a digital output. The sensor outputs a logic one (+3.5V) at the digital output when an object is placed in front of the sensor and logic zero (0V), when there is no object in front of the sensor. An onboard LED is used to indicate the presence of an object. This IR PROXIMITY OBSTACLE SENSOR is designed to work with almost all ARDUINO boards and MICROCONTROLLERs - AVR, PIC, 8051, ARM etc. Operating Voltage: 5V Adjustable Range using preset (potentiometer on board) Since the sensor module works on INFRARED, for obstacles with reflective surfaces (white colored), the maximum range will be higher and for non-reflective surfaces (black colored), and the maximum range will be lower. This can in turn be used for detecting whiteblack lines (in line follower ROBOTs) or brightdark objects (in object identification ROBOTs) Useful for various Robotic Applications, Room Visitor Counter Systems, etc.
