TEMPERATURE AND HUMIDITY MODULE
HTF 3130
Based on the rugged HTS2030SMD humidity sensor, HTF3130 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.
