Pifco Household Automatic Night Light

Product Description

PIFCO AUTOMATIC NIGHT LIGHT keeps your room, office, or hallway nicely lit. It is easy on the eyes for your tiring eyes but bright enough to light your room enough to see.This is a kind of intelligent night light, brightness changing, off under daylight, give out weak light at dusk/dawn, and with full brightness in dark night. Dark light helps to keep your kids calm at night without being as bright as the white light setting. Try it.

The PIFCO AUTOMATIC NIGHT LIGHT features an automatic dusk till dawn feature. Simply plug in your night light and it does the work.

Automatic night lamp as the name suggests is for turning ON and OFF the lamp automatically without the need of human interventions. It senses the light intensity from surroundings and find whether its day or night. And it automatically turns ON when the surrounding is dark and it turns OFF when it receives light from surroundings. A sensor called LDR is used to detect the light intensity. This project finds wide outdoor applications in streets, gardens and public places where it finds difficulty to appoint a person to operate the lights.

This The main part of this circuit is the light dependent resistor (LDR). It is a sensor which is a particular kind of resistor whose resistance decreases when exposed to light. Likewise it offers high resistance in dark. The resistance value changes from few 100 ohms to mega ohm range. The LDR is placed in a potential divider network. So voltage across LDR changes with intensity of light. Voltage across the LDR is given to the positive terminal of a comparator. Now a reference voltage is required to compare with the voltage across LDRexclusive pack feature a spare bulb.

Therefore output of comparator will be high. The output of comparator is given to a transistor wired as a switch. Since enough voltage appears across the base emitter junction, the transistor conducts and current passes through the relay coils. So relay switches its contact and the bulb glows. Bulb is connected to the NO (Normally Open) pin of relay as it should be off when the relay coils are not energized.
