The electronic kit "smart sensor trip unit circuits" offers an exciting and interesting introduction to the world of sensor electronics. In order to ensure easy wiring of the respective components, they are electrically connected with each other using simple pins. The great thing about this is that the pins are pressed into pre-lasered holes without any great pressure.So simply align the assembly plan on the wooden plate, place the components according to the template and connect with the drawing purposes. Everything is already set up and the circuit is ready for operation. And then it says: Have fun experimenting!4 interesting sensor circuits can be built and tested:Fridge light testerChocolate box guardSuction cup detectionWater level controllerAfter experimentation, all components are stored in the self-made wooden box and can be used again and again for new experiments.This text is machine translated.
