Based on the rugged HS1101LF capacitive humidity sensor, HM1520LF is a dedicated humidity transducer designed for measurements at low humidity Direct measurement of dew point or water concentration can be easily obtained in really cost effective conditions. Direct interface with a micro-controller is made possible with the module’s linear voltage output.


  • Tubular form for through wall mounting
  • Product free from Lead, Cr(6+), Cd and Hg
  • Calibrated, linear voltage for easy electronic interface 
  • Typical 1 to 1.6 Volt DC output for 0 to 20% RH at 5Vdc supply 
  • Ratiometric to voltage supply 
  • Patented solid polymer structure 
  • Full interchangeability 
  • Not affected by water immersion 
  • Controlled temperature dependency
  • Humidity Sensor Specific features not affected by long period at low humidity values 
  • High resistance to chemical 
  • Fast response time
