Smart public washroom / Nurul Hidayah Firdaus and Nurul Ain Shafiena Mohd Nazib

This project is about the 'smart automatic washroom' which has automatic lamp using motion detection by PIR sensor and automatic flush. The core of the system is constructed based on the Microchip's PIC16F877A microcontroller as their controller circuit which automatically turns ON the lamp and the flush will automatically do it work when the lamp is switch OFF. The sensor will sense a human motion and then transmit the signal wirelessly. When the sensor senses a human motion in the sensor's detection area, sensor will be triggered and then the washroom's l amp will automatically switch ON. Lamp will automatically OFF when the user going out from the room. As long as PIR sensor does not detect motion in the detection area, the lamp will not function. This project also used automatic flush system. Since the flush are not able to apply in prototype, so using motor as the main component is the best choice. The flush will function right after a few seconds the lamp is switch OFF. However, if the user press the flush button, the flush will not working after the lamp OFF.
