Description
Infrared Sensor Reflective Photoelectric Module for Robotics, DIY Electronics Obstacle Avoidance (Blue)..!
Technical Information Description Light sensor module strong flexible environment, having a pair of infrared transmitter and receiver.
Transmitter to run a certain frequency infrared. When obstacles are encountered in the detection direction,
the IR receiver is reflected back to the receiver tube. After processing through a comparator circuit,
green LED will light up, signal output interface is digital. The output signal (low signal level) can be
adjusted via a potentiometer knob. Effective detection distance range of 2~30cm. Operating voltage is 3.3V-5V.
Range detection sensor can be adjusted via a potentiometer with little noise, easy to assemble, easy to-use.
Can be widely used in robot obstacle avoidance, obstacle avoidance automobile assembly line and black
and white line tracking, as well as in many other cases.
Parameters1. Green LED light for successful obstacle detection signal. 35 degree detection angle. For adjustment, adjust
the potentiometer clockwise, the detection distance increases; Anti-clockwise adjustment of the potentiometer,
the detection distance is reduced.
2. Sensor Active Infrared Reflection Detection, target reflectivity and shape is key to the detection distance.
3. The sensor module output port can be directly connected to the microcontroller I/O port can also be
controlled directly by 5V relay. Connections: VCC-VCC; GND GND; OUT-IO
4. Adopts the LM393 comparator for better stability
5. Can be connected to 3-5V DC power supply. When the power is turned on, the Red light illuminates
6. With 3mm screw holes for easy mounting and installation
7. PCB size: 3.2 * 1.4 cm
8. Each module supplies the threshold voltage comparator with potentiometer
Interface1. VCC external 3.3V-5V voltage pin (5V microcontroller and can be directly connected to 3.3V MCU)
2. GND GND
3. Digital output interface (0 and 1)
