The light sensor module has a strong adaptable to the environment, having a pair of receiver and optical transmitter, launching infrared transmitter certain frequency
When obstacle is encountered in the sensing direction, the infrared receiver is reflected from the receiver tube, after processing through the comparator circuit, the green light turns on while the digital output signal signal output interface (a low level signal) ) be adjusted via potentiometer detection distance knob, the effective range distance 2 ~ 30 cm.
3.3V-5V operating voltage; The sensing range of the sensor be adjusted via the potentiometer, with little interference, easy to assemble, easy to use features.
Robots can be widely used to avoid obstacles, avoid obstacle assembly of cars line counting and monochrome line monitoring and many other occasions.
Interface: external VCC 3.3V-5V voltage (5v microcontroller and can be connected directly to 3.3V MCU); GND GND an external; OUT interface small digital output board (0 and 1);
1; When the module detects an obstacle in front of the signal, the green light levels circuit continuing door of low output signal OUT, the module detects the distance 2 ~ 30cm, detection angle 35, the distance detect potential control to adjust, adjust the potentiometer clockwise, the detection distance increases; counter-clockwise adjustment potentiometer, the detection distance is reduced.
2; The active infrared reflection detection sensor, reflective target and the shape of the key detection distance. The minimum detection distance that max in black and white; small area of ??the small object distance, a large area from the Grand.
3; The OUT output port of the sensor module can be connected directly with the IO microcontroller being driven directly to a 5V; Connection: VCC-VCC; GND-GND; OUT-IO
4; The comparator using LM393, the work's stability;
5; It can be 3-5V DC power supply for the module. When you turn it on, the red light power indicator;
6; With 3mm screw holes for easy mounting, installation;
7; The circuit size: 3.2CM x 1.4CM
8; Each module in the delivery has voltage threshold of the dial gauge adjustable by potentiometer, special circumstances, please do not adjust the potentiometer.
