RELATIVE HUMIDITY MODULE

HM 1500

Based on the rugged HS1101 capacitive humidity sensor, HM1500 is a dedicated humidity transducer

designed for OEM applications where a reliable and accurate measurement is needed. Direct interface with a

micro-controller is made possible with the module’s linear voltage output.
