Description:-

In these busy lives, sleep is important to get ready for the next day. And it was irritating in the middle of the night to wake due to heat and it was more irritating to get up during sleep, put off the AC, and put ON the fan to overcome the heat. So the automatic ac-fan timer does the job for us while we are in sleep, so we have better sleep at night and brisk during the next day. Every day we put a 4-hour timer on the AC at night. after Ac has OFF we woke and turn ON the fan. So I decided to make a timer that turns off the AC after the desired time and turns on the fan.

Automatic AC Turn On-OFF Timer

AC FAN Turn On-OFF Timer

Project Used Hardware

Arduino pro mini, IR led, single channel relay module, 5v power supply, 1k pot.

Project Used Software

Arduino IDE

Project Hardware Software Selection

SOFTWARE:

Arduino IDE - it's easy to program in, and it has many libraries.

HARDWARE:

Arduino pro mini - used here because it's compact in size and does the job.

1K potentiometer - for adjusting the Timer value.

IR LED - to turn ON and turn OFF the AC. Relay costs almost 400rs but for IR led, the cost is 2rs. It is our choice to use Relay or the IR sensor.

5v Single channel relay - to turn ON or OFF the ceiling fan after turning ON or OFF the AC.

5v power supply - it is sufficient to power the Arduino and other components.
