Calling all Model Railroaders (ok, it’s not just for Model Railroading)! Remember our Scale Speedometer and Crossing Light project? We used IR transceivers in the track to detect a train passing overhead. Perfect for block detection and other projects. We are releasing a 6 channel IR sensor board (fully populated) for use with Arduino, Raspberry Pi, PIC and other microcontrollers. Comes with all components, including the 6 IR transceivers wired to 6′ cords. All connections are screw terminals for ease of use. Each phototransistor has a potentiometer for adjusting sensitivity. Operates at 5v or 3.3v (select which version). Comes with sample code for Arduino.
