Automatic Day Night Light Switch Circuit

The entire circuit of this 12 volt day night switch can be built over a small piece of general pcb and the whole assembly along with the transformer may be housed inside a good looking abs plastic enclosure.

Automatic day night light switch circuit.

The working of this night light circuit very simple. The circuit of an automatic night light described in this article can be used to put off a light when day breaks and switch it on back when darkness sets in. The circuit will automatically switch on the ac lamp when night falls and the lamp will be automatically switched off after a preset time. Learn how simple it is to build a 12 volt day night switch.

Since we have 12v ct 12v or 24vct transformer so set this circuit form. We should make a 9 volts dc power supply and connects them together as figure 2 figure 2 block diagram and 9 volts dc regulation of daylight sensor switch circuit. It contains two automatic relay switches which will activate and deactivate according to the sunrise and sunset. At the daytime the relay 1 will become.

The circuit can perform both day night light dark sensing tasks. Automatic daylight sensor switch project then we apply the above circuit to make the automatic air pump. The circuit can be used as a commercial automatic street light control system as a domestic porch light or corridor light controller or simply can be used by any school kid for displaying the feature in his school fair exhibition the following content describes four simple ways of making a. Now switch on the power supplies of the circuit both 6v dc and 230v ac.

A cheap and simple automatic night light using few transistors and ne555 timer is shown here. The 4 simple light activated day night switch circuits explained here can all be used for controlling a load normally a 220v lamp in response to the varying levels of the surrounding ambient light.
