High Speed USB 2.0 Cable For mobile charging||USB Data Cable

Features of IR Sensor Module:-

• When the module detects obstacles in front of the signal, the circuit board green indicator light level, while the OUT port continuous output low-level signals, the module detects a distance of 2 ~ 10cm, detection angle 35 °, the detection distance can be potential adjustment with adjustment potentiometer clockwise, the increase in detection distance; counterclockwise adjustment potentiometer, the detection distance decreased.
• 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 LM393, stable.
• 3-5V 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.
