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
