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.
