Description

Infrared (IR) break-beam sensors are a simple way to detect motion. They work with an emitter side that sends out a beam of human-invisible IR light, then a receiver that is sensitive to that same light. When something passes between the two, its transparent to IR, then the beam is broken and the receiver will let you know.

Compared to PIR sensors, breakbeats are faster and allow better control of where you want to detect the motion. Compared to Sonar modules, they're less expensive. However, you need both monitor and emitter.

This is the 3mm IR version. It works up to 25cm / 10 ″. You can power it from 3.3V or 5V, but 5V will get you better range and what we suggest. The receiver is open collector transistor output which means that you need to pull up resistor if you want to read a digital signal off the signal wire. Most microcontrollers have the ability to turn on a built in pull up resistor. If you do not, connect to 10K resistor between the white wire of the receiver and the red wire. If you want to control a relay or LED, it can sink up to 100mA to ground
