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 […]
Exhaust
Timer Controlled Exhaust Fan Circuit
This simple timer oscillator circuit can be used for automatically switching an exhaust fan ON/OFF as per a fixed predetermined period. The circuit was requested by Mr. Anshuman. Technical Specifications Here is a suggestion for the circuits on your blog. The idea is to have a very simple Oscillating circuit will delays of 5-10 minutes to […]
