This is a 37-in-1 Sensor Kit from keyestudio. It includes digital and analog sensors as well as special modules such as ultrasound, digital tubes, temperature, and humidity. For each module, there is a clear connection diagram and sample code. So it's easy to operate even you are a newbie. You'll surely be able to have a lot of fun with this variety of sensors, can even build a robot!
The sample code of this sensor suite is based on Arduino, it is open source and easy to use. You can also apply this kit to other development platforms such as 51, STM32, Raspberries Pi, micro:bit if you're good at it. The working principle of those platforms is almost the same. Now let's enter the world of robotic sensors and learn together!
