IR Sensor Module

Specifications:

• the sensor active infrared reflection detection, target reflectivity and shape of the detection distance of the key. The black minimum detection range, white maximum; small area object distance is small, a large area from the large.
• The sensor module output port OUT can be directly connected with the microcontroller IO port can also be driven directly to a 5V relay; Connection: VCC-VCC; GND-GND; OUT-IO.
• The comparator using LM358, stable.
• 5V DC power supply module can be used. When the power is turned on, the red power LED is lit.
• With the screw holes of 3mm, easy to install.
• Board size: 3.1CM * 1.5CM.
• Each module in the delivery has threshold comparator voltage adjustable via potentiometer, special circumstances, please do not adjust the potentiometer.
