HTG3500 Series

Compliant with RoHS regulations

RELATIVE HUMIDITY AND TEMPERATURE MODULE

Based on the rugged HUMIREL humidity sensor, the HTG3500 series are dedicated humidity and temperature plug and

play transducers designed for OEM applications where reliable and accurate measurements are needed. Direct interface

with a micro-controller is made possible with the modules humidity linear voltage and direct NTC outputs. The

HTG3500 series are designed for high volume and demanding applications where power consumption is critical.

• HTG3500 SERIES GENERAL CHARACTERISTICS
