Jazuaiao 10Pcs IR 3 Wire Flame Detection Sensors Module Detector Obstacle Avoidance Automatic Door Control

The OUTput port can be directly connection with port of the single chip microcomputer, or it can directly drive a 5V Connection mode: GND-GND When the module detects the front obstacle signals, the green indicators light on the circuit board lights up, and at the same time, the OUT port continuously outputs The detection distance of the module for 2-30cm, and the detection angles is 35 The detection distance can be adjusted by the potentiometer, and the potentiometer is adjusted clockwise to increase the detection distance Adjust the potentiometer counterclockwise to reduce the detection distance The Sensors actively detects IR reflection, so the reflectivity and shape of the targeted is the to the detection distance The detection distance of black is the smallest and that of white is the largest Small-area objects have small distances and large-area objects have large distances With sensitivity knob, the detection distance can be adjusted according to the actual environmental requirements to adapt to different application scenario The comparator adopts LM393, which works stably The module can be power by 3-5V power supply When the power is turned on, the red power indicators lights up
