IR Sensor Module is utilized for a range of applications including robotics, object detection, and visitor counting. It is compatible with platforms such as Arduino, Raspberry Pi, ARM, AVR, PIC, and 8051. This high-accuracy, quality IR sensor features an Infrared Obstacle Avoidance design (Active Low) with a pair of transmitting and receiving tubes. When the emitted light waves are reflected back, the receiving tube captures the IR waves. The onboard voltage comparator circuitry processes the signals, activating the green indicator LED.
