Evaluating and recording the electrical power passing through a circuit at a certain time, a digital Watt-hour meter is a measuring device. We can know how much electrical energy is used by an electrically powered device, a home, and a business just by implementing a Watt-hour meter. At the consumer’s premises to evaluate their electrical usage, electrical utilities generally install watt-hour meters.
In each billing period, the reading is taken. Kilowatt-hour (kWh) is the billing unit. During one hour this is equal to the total usage of electrical energy by a consumer of one kilowatt, and it also equals equal to 3600000 joules.
The arduino kWh Meter is usually referred to as an electrical meter, energy meter or electric meter, or electricity meter.
The watt-hour meter is comprised of mainly a tiny motor and a counter. The motor operation starts by the diversion of the exact fraction of current flowing in the circuit that is to be measured.
The motor’s running or turning speed is directly proportional to the amount of current flowing through the circuit.
