Logging RH without Temp
The Bluetooth-enabled HOBO MX1101 and HOBO MX1102 loggers both use a Relative Humidity sensor that returns a temperature-compensated RH measurement.
USB loggers, such as the HOBO UX100-03, use an RH sensor where temperature compensation is not available, so temperature must be measured if RH is enabled on these loggers.
The temperature-compensation feature of the sensor used in the MX series loggers provides our customers with more flexibility in their use of the logger.
