The operation of the circuit is as follows. The circuit diagram of this device consists of two main components.
Circuit Diagram For Bathroom Light Off Timer
Automatic washroom light switch circuit diagram. Automatic washroom light switch project with circuit diagram and components. Working of the project. There are two important components in this circuit first is pir sensor passive infrared sensor and second is relay. Cd4017 decade counter ic. One end of the reed switch is connected to 5v power supply while the other is connected to the base of bc558 pnp transistor. The code for the automatic room lights using arduino and pir sensor is given below.
This automatic staircase light circuit switch on the staircase lights automatically when someone enters on the stairs and gets off after some time. The automatic room lights using arduino and pir sensor is a simple project where the lights in the room will automatically turn on upon detecting a human motion and stay turned on until the person has left or there is no motion. The operation of the circuit is as follows. When the door opens and closes for the second time the circuit turns off the light by turning off the relay. Also read the post. When the door of the washroom is opened and closed the circuit turns switches on the light using a relay.
Reed switch with magnet available as combination lm741 op amp ic. When the door is opened again the lamp turns off after a very short delay. Operational amplifier ic lm741 and decade counter ic cd4017. Components required reed switch with magnet available as combination lm741 op amp ic cd4017 decade counter ic 5v relay module lamp bc558 pnp transistor. Here is a simple and low cost automatic bathroom light circuit. When the door opens and closes for the second time the circuit turns off the light by turning off the relay.
Automatic washroom light switch circuit diagram. Automatic washroom light switch circuit diagram. The light automatically turns on when the bathroom door is opened and remains lit in the occupied state. The circuit will automatically switch on a washroom light when some one tries to open the washroom door and automatically switch off that light when again opens the door to come out. This automatic circuit saves energy and greatly assists your visitors especially at night. 2 x 10kω resistor 100ω resistor 820ω resistor connecting wires.
