HTM1735LF – Temperature and Relative Humidity Module
DESCRIPTION
Based on the rugged HS1101LF humidity sensor, HTM1735LF is a dedicated humidity and temperature
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 humidity linear voltage and direct NTC
outputs. HTM1735LF is designed for an optimized board to board connection.
