Smart Fan Challenge

Design your Smart Fan, the fan should turn on automatically based on the ambient temperature at the room.

What It has to do?

  • The room is detected as hot when temperature degree is higher than threshold temperature which make people feel uncomfortable. Threshold temperature decide based on the ambient temperature in the room.

  • The temperature sensor will send this signal to micro:bit，and micro:bit send the signal to the fan.

Hardware to be Used

This project uses the following modules from the Neo Beginner Kit:

  • Temperature and Humidity Sensor – Detects temperature and humidity level of the room

  • NeoPixel Ring – If temperature is less than threshold temperature it is pleasant (green)

  • Relay Module – Safely turns the fan ON and OFF

  • DC Motor with Fan – DC Motor with Fan has to be connected to Relay module similar to water pump

  • OLED Display (I2C) – Shows moisture level and pump status

  • Breakout Board + Connection Cables – Plug-and-play connections to micro:bit

Working Model of Smart Fan

  • Connection of the Relay to the fan

Relay Fan Connection

  • When temperature degree is higher than threshold temperature fan turns ON to keep the room comfortable.

Smart Fan ON

  • When temperature degree is less than threshold temperature the fan will automatically stop.

Smart Fan OFF

✅ With a motor and fan, students can begin experimenting with movement, airflow, and automation—skills
