Infrared Sensor (Tracking Module) HS-S01P

1. Introduction

The infrared emission and reception head of the infrared detection (tracking) module is greatly interfered by environmental light, generally speaking, the closer to the reflective surface, the better the effect.The infrared detection (tracking) module has a potentiometer on the back. By adjusting the potentiometer, the threshold of the module can be adjusted to output the corresponding digital signal.Adjusting the voltage of the potentiometer can adjust the detection distance of the infrared sensor.When the LED blue light just extinguishes, the detection distance is the farthest.If the LED blue light is always on or not lighting up, you can adjust the potentiometer.Turn the LED blue light to just off.Operating voltage: 3.3～5V.Check the reaction distance: 1-50mm.
