The "smart sensor-pin circuits" electronics kit offers an exciting and interesting introduction to the world of sensor electronics. In order to ensure simple wiring of the respective components, they are electrically connected to each other using simple pins. The great thing about this is that the pins are pressed into pre-lasered holes without much pressure. So simply align the assembly plan on the wooden board, place the components according to the template and connect them to the pins. Everything is already set up and the circuit is ready for operation. And then it is said: Have fun experimenting! 4 interesting sensor circuits can be set up and tested: Refrigerator light checker, praline box guard, sauCold detection, water level controller. After experimenting, all components are stored in a self-made wooden box and can be used again and again for new experiments.
