HUMIREL HTF3000LF

1
TEMPERATURE AND HUMIDITY MODULE
HTF3000LF
RoHS Compliant
Based on the rugged HS1101LF humidity sensor, HTF3000LF is a dedicated humidity and temperature
transducer designed for OEM applications where a reliable and accurate measurement is needed. It features a
very small size for easy, cost-effective mechanical mounting. Direct interface with a micro-controller is made
possible with the module’s linear frequency output.

Temperature influence on HTF3000LF humidity measurement
For demanding application, temperature coefficient could be compensated over operating temperature
range using following formula :
Rhcorr = RH + 0.08 * ( T – 25 )
Fout Corr = Fout -0,88 * ( T – 25 )
(T in °C, RH in %RH, Fout in Hz )
