Hello,
I am fairly new to 1-wire, though I setup a temperature probe about 4 years
ago with excellent success. Today I am looking to 1-wire to monitor the
voltage on my car battery. It seems to drain over night. I can measure the
voltage at night using a multi-meter (13.1 VDC) and by the morning it is 0.2
VDC. The problem I am not sure if the voltage drop is slow and steady, or
there is a defect in the battery that is causing a sudden drop off.
So I'd like to measure the voltage over time and see what the trend it looks
like.
The question is, what would be an appropriate 1-wire device to measure this
voltage?
The devices that are out there seem to measure lower voltages and I am I'm
not an electrical engineer so I am adept at designing a circuit that would
drop the voltage to an acceptable range without otherwise adversely
affecting the measurements. Though, point me in the right direction and I
can assemble it.
Thank you for your advise,
Jason
