IR Break Beam Sensor - 5mm LEDs - 5 Pairs
Easily detect motion of a passing object with these infra-red beam break sensors from PMD Way.
Each pair includes a transmitter and receiver unit, when an object passes between the two - and its not transparent to infra-red - it breaks the beam and this is reported by the receiver unit.
The receiver is open collector transistor output which means that you do need a 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 a 10K resistor between the white wire of the receiver and the red wire. If you want to control a relay or LED or whatever, it can sink up to 100mA to ground.
Each order of one quantity is for five pairs (a pair being a transmitter and a receiver unit).
