- The sensor module has strong ability to adapt to ambient light. It has a pair of infrared transmitting and receiving tubes. The transmitting tube emits infrared light of a certain frequency.
- Signal output interface outputs a digital signal (a low-level signal). The detection distance can be adjusted by the potentiometer knob. The effective range is 2 to 30cm and the working voltage is 3.3V.5V.
- The sensor's detection distance can be adjusted by a potentiometer, has small interference, is easy to assemble, and is easy to use.
- It can be widely used in robots to avoid obstacles, avoid cars, count pipelines, and track black and white lines.
- Sensor module output port OUT can be directly connected with the microcontroller IO port can also directly drive a 5V relay; connection mode: VCC-VCC; GND-GND; OUT-IO.
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 °, 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 .
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 .
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
Using the comparator LM393, stable ;
Can be used for 3-5V DC power supply modules . When the power is turned on, the red power.
