- 100% Brand New 
- When the module detects the front obstacle signal, the green indicator light on the circuit board is lit, and the OUT port continues to output the low level signal 
- The module detects the distance of 2 ~ 30cm, the detection angle is 35 degrees
- The detection distance can pass the potential device to adjust the clockwise potentiometer, the detection distance increases. 
- Counterclockwise adjustable potentiometer, the detection distance is reduced
- The sensor active infrared reflection detection, so the target reflectivity and shape is the key to detect the distance
- Which black detection distance is the smallest, white is the largest.
- Compatible with lead and lead-free solders
- Small area of the object distance is small, large area distance is far
- The sensor module output port OUT can be directly connected with the microcontroller IO port, also can directly drive a 5V relay
- The comparator using LM393, stable
- It can be used 3-5V DC power supply to the module 
- When the power is on, the red power light is on 
- With 3mm screw holes, easy to install, install 
- Type: Infrared Obstacle Avoidance Module 
- Connection: VCC-VCC, GND-GND, OUT-IO
- The Circuit Board Size: 3.2cm x 1.4cm/1.26" x 0.55" (Approx.) 
- Detected Distance: 2cm - 30cm/0.79" - 11.81" (Approx.) 
- Interface Description (3-wire) 
- VCC: External 3.3V-5V Voltage(Can be directly connected to 5V MCU and 3.3V MCU) 
- GND: GND External 
- OUT: Small Board Digital Output Interfaces (0 and 1)
