Electric appliances consume electricity when they are in standby mode and sometimes even in off-mode. These "losses" of each appliance individually are not large but the sum over all appliances is no longer negligible. The standby losses of ten households are investigated. The standby power varies from 7 to 134 W and has an average of 40 W. The standby consumption is on average 274 kWh/year, representing 8% of the yearly consumption of an average household. With the 1-Watt plan, it is possible to reduce the standby losses to a significantly lower level. This project deals with a microwave oven, which consumes standby power of 3mW is reduced where a low standby power achieved. The microwave oven power consumptions monitored and it is connected to the analog input of the microcontroller. In this simulation we connected the Trim pot for adjusting the current input to the microcontroller. Current consumption goes below 3W the microcontroller turns off the relay. Then the microwave oven power shuts off.
