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

Parameter:

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

the sensor module output OUT can be directly connected to the microcontroller IO port can also be directly driven to a 5V 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 mounting, installation;

Interface:

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

2. GND an external GND;

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