Description
The aim of this project is to develop light intensity depend ac load control replaces system to include dimming feature. LDR according to achieve desired operation.
In the present system, mostly the AC load whose energy consumption is high. Its intensity cannot be controlled according to the requirement so there is a need to switch on to an alternative method of light sensor system i.e., by using LDR. This system is build to overcome the present day drawbacks continues load ON. This system demonstrates the usage of the LDR (light dependent resistor) as the light source and its variable intensity control, according to the environmental light. 555 timer is used as delay switch when fluctuation is course supply fed a regulated.
The power supply consists of a step-down transformer 230/12V, which steps down the mains voltage to 12V AC. This is converted to DC using a bridge rectifier and it is then regulated to +5V using a voltage regulator 7805, which is required for the operation of the comparator and other components.
This system consume less power and its life time is more, as compared to the conventional other system. The more important and interesting feature is its intensity can be controlled according to the light presence.
HIGHLIGHTS
- This project is to develop light intensity depend ac load control
- LDR is according to achieve desired operation

Project got in time. Good service after delivery by video call. They giving one year warranty with peace to peace replacement. I really like service of ELECTROSAL. Thanks team and specially thanks Tulasidas sir who supported me lot in my project ” Automatic Power factor Correction ” .

Great place.
The place where you can change your ideas in real working prototypes & machines.
It is one of your project manufacturing small scale industry in the area.
