TEMPERATURE AND RELATIVE HUMIDITY SENSOR
HTS2030SMD
Meets RoHS regulations
Based on a unique
capacitive cell for humidity
measurement and a
Negative
Temperature Coefficient (NTC)
thermistor for temperature measurement, this dual purpose
relative humidity / temperature miniaturized sensor is designed for high volume,
cost
sensitive applications with tight space constraints.
It is useful in all applications where
dew point, absolute humidity measurements
or humidity compensation are required.
