Hardware Modules 

Building blocks assembled together to form functional modules. 

All-in-one Unit 

Combined energy & temperature monitoring sensor node with web-connected base-station based on Raspberry Pi 

 

 

Sensor Nodes

Open source-energy monitoring transmitter node

emonTx V2 (old)

emonTx Arduino Shield

Arduino compatible energy monitoring shield

emonTH

Low power temperature and humidity monitoring node

 

Displays

emonGLCD (old)

 

Base Stations (emonBase)

Receives data from the transmitter nodes and posts to emoncms server (local, remote or both)

For an overview of all base stations see emonbase overview page

Raspberry Pi

NanodeRF SMT (old)

 

Software Modules

Emoncms

A powerful open-source web-app for processing, logging and visualising energy, temperature and other environmental data.

Firmware GitHub

Arduino IDE compatible firmware sketches and compiled .hex files for hardware modules

All firmware and other software examples can be found on the OpenEnergyMonitor and Emoncms github.
