Help me,
We are going to build digital seismograph using data logger and this
seismograph I'm going to operate in the remote site locations.
My problems I don't have 110-220 vac in the site location but we only
have 12 v dc
from the battery ( + the solar panel) for supply the data logger.
I will be thankful to you (psn-ers) if you have a sollutions on my
problems, Thankyou.
