Today’s energy efficient industrial, appliance and consumer applications, like HVAC, printers and refrigerators, require optimal system performance to meet environmental and end user expectations. TE Connectivity’s (TE) engineering and 20+ years of experience provides humidity and temperature combination sensors with leading response time, precision in measurement and sustained performance even when exposed to extreme changes and conditions. TE’s HTU20/21D senses the true relative humidity and temperature to provide best in class performance and superior value to competitive solutions.


  • Enable optimal system performance and precise engineering with a strict linear response
         curve through humidity (0-100%) and temperature (-40 to 125°C) 
  • Support reliable, consistent system performance driven by properties of TE’s specific
         polymer combined with calibration slope and offset skills
  • Deliver fast response times (t63% in 2 sec) with TE’s humidity die structure
  • Provide precise environment measurement even after high humidity exposure or
         condensation events with TE’s specific die and IP67 rated sealing with filter options
