Temperature/RH Smart Sensor (S-THB-M00x) Manual
11427-N MAN-S-THB
The temperature/RH smart sensor is designed to work with smart sensor-compatible HOBO®
data loggers and stations. All sensor parameters are stored inside the smart sensor, which
automatically communicates configuration information to the logger without any
programming, calibration or extensive user setup.
Specifications
Temperature
RH
Measurement Range
-40°C to 75°C (-40°F to 167°F)
0-100% RH at -40° to 75°C (-40° to
167°F); exposure to conditions
below -20°C (-4°F) or above 95%
RH may temporarily increase the
maximum RH sensor error by an
additional 1%

Drift
<0.1°C (0.18°F) per year
<1% per year typical
Response Time (typical, to 90%
of change)
5 minutes in air moving 1 m/sec
5 minutes in air moving 1 m/sec
with protective cap
Operating Temperature Range
-40°C to 75°C (-40°F to 167°F)
Environmental Rating
Weatherproof: 0 to 100% RH intermittent condensing environments.
For best results, the temp/RH smart sensor should be mounted inside
a protective enclosure, such as a solar radiation shield.
