100% brand new with good quality Product type: hc--sr501 body sensor module Operating voltage range: dc 4.5-20v quiescent current: level output: high 3.3 v /low 0 Color: multi-color Package Contents: Set of 5 Adjust Ir Pyroelectric Infrared PIR...
Repeatable trigger : the sensor output high, the delay period, if there is human activity in its sensing range, the output will remain high until people leave after the high variable delay Low (automatically extended sensor module detects the human body after every activity a
Output high signal : easy docking and all kinds of circuits.
Dimensions: : 1.57 in x 1.02 in x 1.26 in (4.0 cm x 2.6 cm x 3.2 cm)
Feature : This joystick provides a smooth, fluid motion, strong click reply and a straight forward interface.
This module uses a 5V power supply. The PS2 set the two-channel analog output module and one channel of the digital output, the output value respectively corresponding to (X, Y) axis offset, its type is analog; button indicates whether the user...
Specification : Base on LM393 and Thermal sensor designed,Power supply 3.3V or 5V,Output signal adjustable sensitivity,Set aside one voltage comparator circuit(P3) Etc.
The Thermal Sensor Module is used a thermal senor and a LM393 dual differential comparator. You can use the potentiometer adjust the sensitivity. Once close to the heat source, the D1 state LED will light, and output signal is 1.1V~1.9V....
This module integrates DHT11  sensor and other required components on a small PCB. The DHT11 sensor includes a resistive-type humidity measurement component, an NTC temperature measurement component and a high-performance 8-bit microcontroller...
The BMP085 is the fully pin- and function compatible successor of the SMD500, a new generation of high precision digital pressure sensors for consumer applications. The universal C-code SMD500/BMP085 (?BMP085_SMD500_API?) is fully upward compatible...
