Measure DC current (12 Volt)
Posted: Tue Dec 25, 2012 8:36 pm
I recently (last weekend) replaced my HP Microserver by a self-build Intel I5 processor server running ESX. The server is powered by PicoPSU powersuply running on a 12 V DC power adapter.
When i open the utility room (meterkast) i find a bunch of poweradapters:
- Solcon fibre modem
- Fritzbox router
- USB hub
- Netgear switch
- RFXcom transciever
And now the new server.
A few of the devices are measured by a Plugwise plug.
Now i am considering building a 12 V powerdistribution with a batterybackup (a normal car battery maybe???) and measure al the devices with a arduino (clone)
I guess i have to use (little?) shunts and measure the voltage drop over the shunt.
I would like to see the measured values in a simple html page, from where i can grab the values and put them in Emoncms.
Any things i have to look at?
