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鈥檚 linear
frequency output.
