The project Current detector cum controller is very much useful for controlling the load in any industry. In this project we are measuring the current consumed by all the loads connected in a house. If the load current exceed the set value of current the load will be disconnected immediately. The heart of the project is microcontroller AT89S51 and current sensing transformer.

The current sensing transformer is used to sense the current consumed by load. The current sensed by the current sensor is converted into voltage and feed to the ADC0804 for analog to digital conversion. The digital equivalent of the current is read by microcontroller AT89S51 from the ADC0804. The digital value of current is processed my microcontroller and displayed on LCD.
