RELATIVE HUMIDITY MODULE
HM1500LF
Compliant with RoHS recommendations
Based on the rugged HS1101LF capacitive humidity sensor, HM1500LF 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.
