HTF3226LF – Temperature and Humidity Module
DESCRIPTION
Based on the rugged HS1101LF humidity sensor, HTF3226LF is a dedicated humidity and temperature
transducer designed for OEM applications where a reliable and accurate measurement is needed. It features a
miniature connector for easy, cost-effective mechanical mounting. Direct interface with a micro-controller is
made possible with the module’s linear frequency output.
