The effective distance range 2 ~ 30 cm, operating voltage is 3.3 V-5 V. the detection range of the sensor can be through the potentiometer, with a small interference, easy to assemble, easy to use functions, the robot can avoid obstacles.



the module detects at a distance of 2 ~ 30 cm, detection angle 35 °, with the potentiometer you can tap the distance,

the sensor module output OUT can be directly connected with the microcontroller io port can also be directly powered to a 5 V relay; connection: VCC-VCC; GND-GND; OUT-IO

the comparator using LM393, job stability;

Power supply 3-5 V DC

with 3mm screw holes for easy assembly, installation;




1. VCC external 3.3 V-5 V voltage (5 v microcontroller and directly on 3.3 v MCU);

2. GND an external SNE;

3. OUT small board digital output interfaces (0 and 1);
