Arduino Infrared Obstacle-Avoiding Sensor

Special Sensor For Robot

Description：

This adjustable obstacle avoidance sensors module is specifically designed for robot development. It is  well adaptable to surrounding light with strong anti-interfer property. It has a unique sending module both from left and right, and an IR receiver in the middle.

Detection Principle :

Sending tube emits infrared ray of certain frequency. When the infrared ray meets an obstacle(reflection surface), it is reflected and received by receiver. Then the corresponding indicator light is on. After processing the reflected signal by the circuit, digital signal is output through signal output interface. Detection distance can be adjusted through potentiometer knob between 2 ~ 50cm. Working voltage is 5V. It is suitable for a variety of microcontroller, such as Arduino controller. It can be installed on robot to detect the surrounding environment changes.
