TRUSTECH GP2Y0A21YK0F Sharp IR Analog Distance Sensor 10-80cm + Cable, A_rduino Compatible Electronic Components Electronic Hobby Kit

The Sharp GP2Y0A21 IR Infrared Distance Sensor is an analog proximity sensor with a range of 10-80cm. The GP2Y0A21 is a distance measuring sensor unit composed of a position sensitive detector (PSD), infrared emitting diode (IRED), and signal processing circuit. This device outputs the voltage corresponding to the detection distance. So this sensor can also be used as a proximity sensor. It provides accurate distance measurement (up to 80cm). Factors such as the reflectivity of the object, the environmental temperature, and the operating duration are not affected easily for distance detection because of the sensor's triangulation of the emitted signal. This sensor package makes it easy to connect it to your microcontroller board or single-board computer! The 3 pins correspond to power (VCC, GND), and an analog voltage signal proportional to the distance to an object (if present). Features: Accurately measure distance to an object indoor or outdoor. Range: 10~80cm Simply supply power and connect the analog output to your Ar-duino, ESP8266, Raspberry Pi, etc Operating voltage of 4.5~5V DC Easy-to-use out of the box by connecting the included 3-pin JST cable. 1 x Infrared IR 10~80cm Analog Distance/Proximity Sensor for Ar-duino Raspberry Pi
