Description

• Can be used for 3-5V DC power supply modules. It has a red power indicator.
• IR Infrared Obstacle Avoidance Sensor Module can be widely used in robot obstacle avoidance, obstacle avoidance car, line count, black and white line tracking, and so on
• The output port OUT sensor module can be directly connected to the microcontroller IO port, you can directly drive a 5V relay
• It has a pair of infrared transmitting and receiving tube, tube infrared emit a certain frequency, when detecting direction meets with obstacles (reflecting surface), and reflected infrared receiving tube, after the comparator circuit processing, a green indicator will light up, at the same time signal output interface to output digital signal (a low-level signal).
