An IR transmitter is oriented towards the TSOP4838 infrared receiver of counter module and objects are moved between the two modules. Each time an object passes between the two modules, the seven segments display show increment in numbers.
Comes as a pack of parts kit and is easily assembled if you can follow the silkscreen indicators(labels) and have beginning experience with a soldering iron. You will need to read the resistor bands or use a multimeter to determine the resistor sizes.
