Obstacle Avoidance IR Sensor Infrared Module Arduino Raspberry
 
Product Information
 
1. When the module detects obstacles in front of the signal, the green LED indicator on the circuit board light level and at the same time the OUT port output low level signal.
The detection module Range from 2 ~ 30cm, 35°detection Angle, test distance can be adjusted through the potentiometer, adjustable potentiometer clockwise, the detection distance increases; Counter-clockwise tuning potentiometer, detection distance is reduced.
2. Sensors, active infrared reflection detection, therefore the reflectivity and shape of the target is the key of the detection range. White one black detection range, minimum maximum; Small area of the object distance, large distance.
3. The sensor module output port OUT can be directly connected to a microcontroller IO port, it can also drive a 5v relay directly.
Connection mode: the VCC - VCC; GND - GND; The OUT - the IO.
4. The comparator is an LM393, giving good stability.
5. Supply Voltage range 3 - 5v dc,  When power is connected, the red power indicator lights.
6. 3 mm screw holes, easy fixed, installation.
7. circuit board size: 3.2CM*1.4CM
8. Each module is shipped already at a reasonable compare threshold voltage, please do not arbitrarily adjust the potentiometer.

Module interface specification:
1. VCC voltage is 3.3V to 5V converter (which can be directly connected to 5V single-chip microcontroller and 3.3V)
2. GND external GND
3. OUT of small plate digital output interface (0 and 1)
