Abstract
A power level meter and method for an AC electrical appliance that can be implemented in the plug of the appliance, monitoring power in response load on the appliance and/or implemented as a module into which an existing appliance is inserted, thereby providing a retrofit solution for appliance AC current monitoring. By using thermo chromic ink and a heat generating resistor, the meter will display different colors on its face to illustrate electrical current flow or demand.
Claims5
A monitoring apparatus for electrical appliances having a plug, a load, and requiring no more than two electrical current conductors connecting said plug to said load, said apparatus comprising:
- a resistor to heat thermo chromic ink that is located between the wall outlet and the load or appliance.
