A new, intelligent, chilled mirror humidity instrument has been designed
for use on buoys and ships. The design goal is to make high quality dew point
temperature measurements for a period of up to one year from an unattended
platform, while consuming as little power as possible. Nominal system accuracy
is 0.3°C, and a measure of data quality is provided to indicate possible drift in
calibration. Energy consumption is typically 800 Joules per measurement; standby
power consumption is 0.05 watts. Control of the instrument is managed by an onboard
central processing unit which is programmable in BASIC, and communication
to an external data logger is provided through an RS232 compatible interface. This
report describes the preliminary sensor tests that led to this new design and provides
the complete technical description required for fabrication.
