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.

* Maximum 100% RH readings are only logged with RX3000 stations. The maximum readings for this sensor with U30 and
H21 stations is approximately 99.99%.
** A single HOBO station can accommodate 15 data channels and up to 100 m (328 ft) of smart sensor cable (the digital
communications portion of the sensor cables).

For best results, protect the temp/RH sensor from sunlight and direct
splashing by mounting it inside a protective enclosure, such as a solar
radiation shield.
