limitless products IR Proximity Sensor for line follower and Obstacle sensing Robots - IR Sensor (Pack of 10) Security Circuit and Motion Detector Electronic Hobby Kit

This is an Infrared based proximity sensor which are great for obstacle avoidance and line following robots. Our infrared transceiver module contains an infrared transmitter and a receiver fit in a compact form on a tiny board. Transmitter emits infrared light and another receiver (photo-transistor) receives that IR light after reflection. The module can be used to identify an obstacle or a nearest object - Onboard LED indicates if the module is connected properly - Another onboard LED indicates when threshold values are touched (turns on) - Great for DIY projects and Arduino beginners - M3 Mounting holes to mount the module on your desk or project - Proximity range up to 7 centimeters depending on the obstructing object and surrounding environment.
