TECHNICAL DATA

RELATIVE HUMIDITY/ TEMPERATURE MODULE

HTM2500

1

Based on the rugged HTS2010 humidity / temperature sensor , HTM2500 is a dedicated

humidity and temperature transducer designed for OEM applications where a reliable

and accurate measurement is needed. Direct interface with a micro-controller

is made possible with the module’s humidity linear voltage output.

Peak conditions: less than 10% of the operational time.
