Smart Bathroom Exhaust Fan Controller Circuit with Sensors

Last Updated on July 1, 2025 by Swagatam 13 Comments

So here we are now making one automatic smart exhaust fan controller system using Arduino UNO which will work for three bathrooms that are all connected to a single ventilation pipe and one common exhaust fan. This whole project is going to be based on PIR sensors for human detection, VOC sensors for odor detection […]
