5pcs Infrared Sensor Infrared Obstacle Avoidance Sensor Module for Smart Car Robot,Sensor
Description: The sensor module is adjustable to the ambient light.It has a pair of infrared transmitting and receiving tubes.The transmitting tube emits a certain frequency IR, which is reflected when detecting obstacles (reflective surface) and received by the receiver tube. After processing with the comparator circuit, the light turns green and the signal output interface outputs a digital signal (a low voltage level signal).The detection distance can be adjusted with the potentiometer. The effective distance range is 2~60cm, the working voltage is 3.3V to 5V. Specifications: Working voltage: 3.3~5V Detection range: 2~30cm Detection angle: 35° Wiring: VCC-VCC;GND-GND;OUT -IO Size: 4 × 1.5 cm / 1.5 × 0.6 in Quantity: 5pcs Weight: 3 g (approx.) Module interface: VCC: External connection of 3.3V-5V voltage (can be directly connected to 5V microcontroller and 3.3V microcontroller can be connected) GND: External GND OUT: Digital output (0 and 1) Scope of delivery: 5 × Modules
Product Features
- If that Signal module detects obstacles, the green indicator light on the board lights up and at the same time the OUT port outputs a low level signal. The detection distance can be adjusted with the potentiometer clockwise to increase the detection distance and counterclockwise to increase the detection distance
- Infrared sensor can be widely used for robot obstacle avoidance, obstacle avoidance car, assembly line, black and white line tracking and many other occasions.
- Active infrared reflection detection sensor, therefore The reflectivity and shape of the target are the keys to the detection range. Black color has the minimum detection range, White has the maximum. Small objects have a short detection range, large objects have a long detection range
- The detection range of the sensor uses the LM393 chips, can be adjusted with potentiometer, little interference, stable performance, easy to assemble and use.
- The output port OUT of the sensor module can be directly connected to the I/O port of the microcontroller. A 5 V relay can also be controlled directly. Can use 3 to 5V DC power supply. When turned on, the red power indicator lights up. Each module is already set and compare the voltage threshold with the potentiometer, so do not adjust the potentiometer arbitrarily
