emonTx stands for Energy Monitoring Transmitter. It’s a small, open source wireless energy monitoring node. It’s based on the Arduino (Atmega328) and is fully compatible with the Arduino IDE and programmed via an FTDI to USB cable.
It’s designed to take inputs from multiple CT sensors, optically from a pulse-output utility meter and from multiple one-wire temperature sensors, and interface via RF with the Nanode which then makes the data available over the Internet. The emonTx is designed to be powered by 2x AA batteries or 5V USB. [via]

Nanode is a low cost Arduino-like sensor node board intended for web connectivity applications. It allows you to develop web based sensor and control systems – giving you web access to six analogue sensor lines and six digital I/O lines. The schematic and other details can be found on the project’s Thingiverse page. The code can be found here.
This is an open source project conceived, designed, manufactured and coded by London Hackspace members.
