Specification Brand : Gump's grocery BulletPoint : Sensors BulletPoint1 : 1. The sensor active infrared reflection detection, target reflectivity and shape of the detection distance of the key. The minimum detection distance which black and white max; small area of the object distance is small, a large area from the Grand BulletPoint2 : 2. 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 BulletPoint3 : 3. The comparator using LM393, job stability BulletPoint4 : 4. Can be 3-5V DC power supply for the module. When the power is turned on, the red power indicator light; with 3mm screw holes for easy mounting, installation; the circuit board size: 3.2CM * 1.4CM BulletPoint5 : 5. Each module in the delivery has threshold comparator voltage adjustable via potentiometer, special circumstances, please do not adjust the potentiometer.
