Method for monitoring of energy consumption amount in lighting field by sensing switch

A method for measuring the amount of electricity used of the electric lamp is provided to measure the power consumption measurement of the electric lamp although the other electric heating appliance is mixed, and to monitor the power consumption in the remote site. The monitoring method comprises the total consumption power calculation(S400) of the switch electric lamp registration(S100), motion detection(S200), operation collection(S300), discrete electric lamp, and the monitoring(S500) and maintenance and repair step(S600). The respective ID is given to the switch operation sensor and the information about the electric lamp is stored in the DB server. The switch moving detector is installed and the On/Off information of the switch is transmitted to the switch operation collector. The total consumption power is calculated based on the electric lamp information stored in the DB server.
