Overview of automated washroom light switch circuit
The Automatic Washroom Light Switch Circuit is a circuit that activates a relay switch that controls the light systems in a washroom automatically. It makes use of sensors and microcontrollers to detect when someone enters the washroom and then turns on the lights. Once the individual leaves the washroom, the circuit is programmed to turn off and save energy. The circuit is easy to build and can be configured to function automatically with current lights or installed with new lighting systems. The circuit uses a passive infrared sensor that is triggered by body heat that enters the detection area, and then sends a signal to the microcontroller, which activates the relay circuit.

Working Principle
Explanation of how automated washroom light switch circuit works
The automated washroom light switch circuit uses a reed switch that is placed on the door of the washroom and a magnet on the frame of the door. When the door is opened and the magnet is moved away from the reed switch, the switch opens and provides an interrupt signal to the circuit. This interrupt signal is amplified by the LM741 Op-Amp and then fed to the CD4017 Decade Counter IC, which produces an accurate time delay of a few seconds before activating the relay.
Once the time delay is over, the relay switches on and provides power to the lamp in the washroom. The lamp remains on until the door is closed and the magnet comes close to the reed switch, which in turn provides another interrupt signal, this time to turn off the relay. The BC558 PNP Transistor amplifies the switch signal and switches the relay on or off. In this way, the circuit ensures that the washroom light is only on when someone is in the washroom, which leads to power savings and extends the life of the light bulbs.
