Toilet Odour Detection Using Fuzzy Logic Technique

The cleanliness of the toilet is very important for human beings. Germs and bacteria start spreading on the human body from here. That is why toilets need to be sanitized and cleaned every day. You have noticed a foul smell in a school’s/college’s/public restroom. It is always a challenge to keep toilets clean because even with frequent, diligent cleaning, odours can persist. It takes special, precise methods and products to prevent school/college toilets from becoming problems. To overcome this, an Arduino-based device to detect bad odors. Device consists of an odour-detecting sensor (humidity sensor, odour sensor, electronic nose) that detects bad odours and informs authorities through SMS (using interface GSM module) and phone call (using PSR module). The device can be mounted on the wall of a toilet. By using this device, students can stay healthy. Additionally, it may reduce some unpleasant diseases. Also, the management is able to reduce the manpoitr and call workers when needed
