Cảm biến hồng ngoại tự động IR cho robot xe hơi thông minh

Specifications: When the module detects the front obstacle signal, the green indicator light on the circuit board is lit, and the OUT port continues to output the low level signal. The module detects the distance of 2 ~ 30cm, the detection angle is 35 °. The detection distance can pass the potential device to adjust the clockwise potentiometer, the detection distance increases. Counterclockwise adjustable potentiometer, the detection distance is reduced. The sensor active infrared reflection detection, so the target reflectivity and shape is the key to detect the distance. Which black detection distance is the smallest, white is the largest. Small area of ​​the object distance is small, large area distance is far. The sensor module output port OUT can be directly connected with the microcontroller IO port, also can directly drive a 5V relay. The comparator using LM393, stable. It can be used 3-5V DC power supply to the module. When the power is on, the red power light is on. With 3mm screw holes, easy to install, install. Type: Infrared Obstacle Avoidance Module Quantity: 1Pc Connection: VCC-VCC, GND-GND, OUT-IO The Circuit Board Size: 3.2cm x 1.4cm/1.26" x 0.55" (Approx.) Detected Distance: 2cm - 30cm/0.79" - 11.81" (Approx.) Interface Description (3-wire): VCC: External 3.3V-5V Voltage(Can be directly connected to 5V MCU and 3.3V MCU) GND: GND External OUT: Small Board Digital Output Interfaces(0 and 1) Notes: Each module has been in the delivery of the threshold voltage comparison through the potentiometer adjustment, do not arbitrarily adjust the potentiometer unless exceptional circumstances. Due to the light and screen setting difference, the items color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
