| HM1520LF Relative Humidity Module • 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 Volt DC output for 0 to 20% RH at 5Vdc supply • Ratiometric to voltage supply • Patented solid polymer structure 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. • 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 • Low Humidity • Meteorology PERFORMANCE SPECS MAXIMUM RATINGS Ratings Storage Temperature Symbol Tstg Value -30 to 70 Storage Humidity RHstg 0 to 100 Supply Voltage Peak Humidity Operating Range 0 to 100 Temperature Operating Range -40 to 60 Peak conditions less than 10% of the operating time.
