IR Infrared Obstacle Avoidance Sensor Module Reflective Photoelectric Module 3..
$8.94Price
- When the module detects the signal of the obstacle ahead, the circuit board on the green indicator light level, while the OUT port continues to output a low-level signal, the module detection distance of 2 ~ 7cm, the detection angle of 35 °, the detection distance can be adjusted through the potentiometer, clockwise potentiometer, the detection distance increases; counterclockwise potentiometer, the detection distance decreases.
- the sensor active infrared reflection detection, so the target reflectivity and shape is the key to the detection distance. Black detection distance is the smallest, white is the largest; small area object distance is small, large area distance is large. 3, the sensor module output port OUT can be directly connected to the microcontroller IO port, you can also directly drive a 5V relay; connection: VCC-VCC; GND-GND; OUT-IO
- 3-5V DC power supply can be used to power the module. When the power supply is turned on, the red power indicator lights up
