Four students from Zilla Parishad High School (ZPHS) Reghendu in Peddapalli have built a toilet flush and hand wash alert system. The system can detect if the user did or did not flush the toilet or wash their hands. If they don’t, it alerts them to. They used an IR sensor to detect the opening and closing of the door, a water sensor to detect the water flow from the flush tank, and a vibration sensor in the sink to detect the usage of tap water.
