IR Light Barrier 4m

The IR-Break-Beam light barriers detect motion by emitting an invisible IR light and using a receiver that detects when something passes between them and blocks the beam. This model has a range of up to 4 m, a fast response time of 0.5ms, and can be used at temperatures from -10°C to 60°C. It is small and easy to install, it is powered by 5V DC, and can be used with Arduino for motion detection, speed capture, and timing in competitions.
