MBED Class 0.1 Energy Monitor/Meter and Solar / Load Controller Scada

Page last updated 31 Mar 2014, by Hardcore Developer. 2 replies

Hey guys!! We built a 24Bit Energy Monitor / Controller around the MBED platform... Right now it supports SNMP access and UDP streaming of values as well as an onboard web server and web based oscilloscope..

It has 8 24 bit Analog Inputs with internal Programmable Gain Amplifiers and 8 N-Channel Mosfet Outputs to control DC loads

Data can be logged in Cacti or Zabbix via SNMP or fed to emoncms (runs on any linux server, http://emoncms.org/) for nice visualization of historical records.

Since the boards Ethernet implementation is identical to the original LPC1768 MBED all existing code is compatible.

I'll be exporting the code from Keil to the online compiler shortily.. Hardware is also avilable at

We have an android app and a desktop application for configuring the boards.

This is really cool! In a future update, consider adding power-over-ethernet, it seems like it'd be ideal for a board like this.

I'm impressed that a single 8 ch ADC chip handles all these input types without external components or overvoltage, overcurrent protection.

It seems the Texas Instruments ADS131 might be a good fit for the analog frontend? http://www.digikey.com/product-search/en?FV=fff40027%2Cfff801eb&k=ADS131
