According to World Energy Outlook (WEO), electricity demand is projected to grow at 2.1% per year until 2040, and this will raise more environmental and economical challenges.

Therefore, I would like to present this prototype of a smart ceiling fan regulator which can help to reduce electricity consumption in public places (e.g, restaurants, laundry shops, and train stations).

The smart regulator receives the video feed from CCTV camera(s) to detect the number of individuals present, also it has a built-in sensor to measure the surrounding temperature.

Then the regulator utilizes these two pieces of information to switch on the fan and control its speed.

Upload the arduino code ./arduino/fan_controller.ino to the UNO board (info).

Run main.py from the command line.
