Can someone suggest a a way to measure DC voltage in the range 10 to 14 volts?I know nothing about circuits but do have basic soldering skills and have built a few small kits.At one location I am using owfs to monitor solar, humidity and, barometric pressure using a a Raspberry Pi and HobbyBoards serial master and sensors.The voltage sensor would be on a a different Raspberry Pi.Thank you,Peter
You can choose something from this

I can remember the name but I think that the chip form barometer can measure up to 12V.
What are you measuring? You can use a voltage divider(look at wikipedia) to lower the voltage for acceptable level not above 12V.
