Arduino and internet based wireless device for monitoring electricity consumption is designed to substitute manual and conventional measurement system. This device consists of sensor, processor, display and network. 

The sensor consists of current transformer and AC to AC Power Adapter. The processor is Arduino UNO which process sensor output. Liquid crystal device (LCD) is used to display real time output. The last part of the device is network composed of Ethernet Shield, 3G Modem for communication with Database Server as data further processing and storage.

The testing with nominal total load 120 watt shows that Vrms value on LCD of the device is 218 volt, Vrms value measured with clamp meter is 216 volt. Irms value on LCD of the device is 0,44 ampere, Irms value measured with clamp meter 0,5 ampere. The real power value on LCD of the device is 92 watt, the real power value measured with clamp meter is 84 watt. The power factor value on LCD of the device is 0,97, the power factor value measured with clamp meter is 0,99.

Keywords wireless monitoring, Vrms, Irms, real power, power factor.
