HM1520LF
Compliant with RoHS recommendations
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.
MAIN FEATURES
Tubular form for through wall mounting Product free from Lead, Cr(6+), Cd and Hg Not affected by water condensation Full interchangeability Typical 1 to 1.6 Volt DC output for 0 to 20% RH at 5 V DC supply Calibrated, linear voltage for easy electronic interface Controlled temperature dependency Ratiometric to voltage supply
HUMIDITY SENSOR SPECIFIC FEATURES
No affected by long period at low humidity values Patented solid polymer structure High resistance to chemical Fast response time
