1 TECHNICAL DATA
TEMPERATURE AND RELATIVE HUMIDITY SENSOR HTS2010SMD
Based on a unique capacitive cell for humidity measurement and a Negative Temperature
Coefficient (NTC) thermistor for temperature measurement, this dual purpose relative humidity / tempe-
rature 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 humi-
dity compensation are required.
MAIN FEATURES
● Miniature Surface mount SMD package
● Compatible with automated assembly processes, including wave soldering,
water immersion and reflow soldering
● Full interchangeability with no calibration required in standard conditions
● High reliability and long term stability
● Available in tape and reel for automatic pick and place
● Individual marking for compliance to stringent traceability requirements
