non-intrusive load monitoring using pic

[enamshah]

I am doing a project on non-intrusive load monitoring using pic.can any body help me.

 

[wizpic]

What type of load ?
what Pic ?
What language ?
You've not given us much to go off there

use current transformer for measuring current and ordinary mains transformer for voltage. Using suitable burden resistor,feed them to pic adc.

for a current transformer you would have to put it in series with the load, this means cutting a high voltage line, which could be unsafe.

A better solution would be a hall effect sensor, similar to the ones used in clamp meters, unfortunately I have no idea where you can get these...

 

[erio]

no there is no need to cutting high tension line, just use split core current transformer and clip it with "LIVE" line of mains. like this one Home | OpenEnergyMonitor

In this project i have to monitor the electric loads(appliances/end devices) in a room using current and voltage sensors at the main power supply of the room.I have to display ON/OFF states of the applliances and also the power consumption of each load on a display.i am using pic micro controller.
