Features:1. When the module detects an obstacle in front of the signal , the green indicator light on the board level , while low-level continuous output signal OUT port , the module detects the distance 2 ~ 30cm, detection angle 35 Â°, the distance can detect potential is adjusted clockwise adjustment potentiometer to detect the distance increases ; counterclockwise to adjust the potentiometer to reduce the detection distance. 2.Active infrared sensors to detect the reflected , and thus the shape of the reflectivity of the target detection range is critical. The minimum detection distance which black , white maximum ; small objects from a small area , a large area from the Grand. 3. The output port OUT sensor module can be directly connected to the microcontroller IO port , you can directly drive a 5V relay ; Connection : VCC-VCC; GND-GND; OUT-IO. 4.Using the comparator LM393, stable ; 5.Can be used for 3-5V DC power supply modules. When the power is turned on, the red power indicator light ; 6. With the screw holes of 3mm , easy fixed installation ; 7. Board size :3.1* 1.5cm-1.2*0.6inch. 8. Each module shipments comparing the threshold voltage has been adjusted by the potentiometer is good , not exceptional circumstances, do not arbitrarily adjust the potentiometer.
Module interface specification:1. VCC: external 3.3V-5V voltage (can be directly connected to 5v MCU and 3.3v MCU) 2. GND: GND External 3. OUT: small board digital output interfaces (0 and 1)
Note:Due to lighting effects, monitor's brightness , contrast settings etc, there could be some slight differences in the color tone of the pictures and the actual item.
