This is keyestudio sensor learning kit. We bring together 37 basic sensors and modules, aiming for the convenient learning for starters. Inside this box, there are digital and analog sensors and also some special modules such as ultrasonic, Bluetooth, acceleration module,etc. 
For each module, there is clear connection diagram and sample code. So even if you are totally new at this, you can get started easily.The sample codes for this sensor kit are based on ARDUINO because it's open source and easy to use. If you are good at this, you can also apply this kit to other MCU development platforms, such as 51, STM32, Raspberries Pi. The working principle is pretty much the same.
