The ElecFreaks Classroom Smart Air Purifier Kit is an engaging educational tool designed for hands-on learning with the micro:bit development board. This kit includes the IOT:bit expansion board, a motor fan, and a dust sensor, enabling students to explore smart home projects while gaining practical experience with sensors and coding. With the included components, users can simulate monitoring and improving indoor air quality. The dust sensor measures air quality in real-time, sending data to the micro:bit. If the dust concentration surpasses a defined threshold, the micro:bit activates the motor fan, which circulates and purifies the air, enhancing indoor air quality. This kit not only introduces the principles of sensors and motors but also fosters environmental awareness and promotes health-conscious thinking. Students can customize air quality parameters by adjusting the dust sensor threshold and programming the fan's operation, creating an interactive and educational experience.
