Description

Automatic Night Lamp with Morning Alarm is a very uniquely designed staff for your daily life. It contains both a lamp and an alarm system. The night lamp automatically turns on when the bedroom light is off. The lamp remains on until it detects daylight in the morning. A bright and cool white LED is used as the night lamp. And when the sensor detects the sun rays in the room it emits a melodious alarm in the morning.

This Smart Light With Alarm detects light by using a sensor called a Light Dependent Resistor (LDR), similar to the way our eyes work. When the sunlight comes, it automatically turns off the lights and activates the alarm. By using this system, electric energy is also reduced because nowadays the manually operated street lights are not switched off even when the sunlight comes and also switched on earlier before sunset.

In this Morning Alarm With Light project, you no need for a manual operation like ON time and OFF time setting. LDR and transistors are the main components of the project. The resistance of the light dependant resistor (LDR) varies according to the light falling on it.
