This project consists of 4 major parts of circuit such as power supply, transmitter and receiver for infrared sensor, and water level sensor. The function of water level sensor was the most important in this project as it is used to control the cleanliness of the toilet. The water level sensor was connected to power supply circuit. The power supply circuit will convert from 12V AC to 9V DC. The water level sensor will control the amount of water that fill in the water tank. User of the toilet can out from the toilet if only the water tank was flushed. This water level sensor will produced solenoid retraction as an output to allow user open the toilets’ door.
