This Smart Auto Toilet System is a project that basically used switching concept by using water level detector circuit and infrared circuit to control the output of the on/off magnetic door circuitry. The aim of the project is to study the relationship between the automatic toilet door system and the water level in high or low condition. The project functionality had been optimized by using Proteus software as to visualize it to get the expected result before the hardware and design prototype of the project was fabricated. To get the output result, an electrical equipment such as multimeter was used to check the continuity of the circuit to ensure that the project can run smoothly as this project was mostly depend on the hardware functionality. The result for this project after hardware implementation is that the detection of human by using passive infrared sensor will energize the relay located on the infrared circuit. As the result, the infrared sensor will energized the on/off magnetic door circuit thus activate the electromagnetic door to be in lock state. To unlock the electromagnetic door, water detector circuit will be used to detect the water level of the project. The water detector functions when the water level is at low state. The relay for water detector will be energize as the water level is low thus dis-energized the on/off magnetic door relay and as the result, the electromagnetic door will be unlocked. It is observed that the project is suitable to be implemented on a public toilet as to increase the awareness of the public toward cleanliness and to be concern about safety matter
