Obstacle Avoidance Infrared Sensor Module Reflection Photoelectric Sensor Board for Tracking Smart Car

Module Parameters:
1. when the module detects obstacles in front of the signal, the green indicator on the circuit board light level and at the same time the OUT port output low level signal, the detection module 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 the microcontroller IO port can, also can drive a 5v relay directly; Connection mode: the VCC - VCC; GND - GND; The OUT - the IO
4. the comparator USES the LM393, working stability;
5. can be used for 3 to 5v dc power to power supply module. When power on, the red power indicator light lit;
6. 3 mm screw holes, easy fixed, installation;
7. circuit board size: 3.2CM*1.4CM
8. each module is shipped already compare threshold voltage through the potentiometer to adjust good, not special circumstances, 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)
