Open source energy monitoring system

This is fully featured energy monitor based on Atmega328 microcontroller which is compatible with Arduino IDE. It is based on JeeNodeV5 for easy expandability. Device has two CT monitoring channels that reads electricity consumption by using energy CT sensors. Also it is features with pulse counting input that can read water or gas meter optically or from direct output.

emonTX has a dedicated port for 1-wire DS18B20 temperature sensor input. As these are stackable so it can read multiple sensors from single line. Energy meter can be battery powered so it can be attached anywhere and communicate wireless nanode that accepts data and publishes online via pachube service.
