This sensor kit contains 48 kinds of commonly used sensor modules in playing the microcontroller, such as active buzzer module, 5V relay module, temperature and humidity module, and so on. It is compatible with various microcontrollers and Raspberry Pi. At the same time, we also provide some detailed projects for each sensor based on the development board, including wiring method, test code, etc. It can help you have a further understanding of those sensor modules and can apply them to interactive projects. Note that in the following projects, the mainboard and other wires are not included in this kit. You need to prepare them by yourself.
