ELECFREAKS micro:bit Classroom Smart Air Purifier Kit

The ELECFREAKS Classroom Smart Air Purifier Kit includes components such as the IOT:bit expansion board, motor fan and dust sensor. These components can perform a variety of functions and perfectly match the micro:bit development board, allowing you to explore more interesting smart home projects.We will simulate the process of detecting and improving indoor air quality using a dust sensor and a motor fan from the Octopus series. The dust sensor detects the dust concentration in the indoor air in real time and transmits the data to the micro:bit, which sends a signal to activate the motor fan when the dust concentration exceeds a certain threshold. The motor fan is attached to the side of the small house and when it receives the signal, it automatically turns on and starts blowing the air in the room. The operation of the fan circulates the air in the room, effectively purifying the air in the room and improving the air quality.ELECFREAKS Classroom Smart Air Purifier Kit not only helps students understand and learn the principles of sensors and motors, but also develops their awareness of environmental protection and health. Students can customize the air quality criteria by setting the threshold of the dust sensor and control the operation of the motor fan by writing code.
