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.
