Relative Humidity sensor - HM1520/HM1520LF 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 moduleâ??s linear voltage output. Main Features * Tubular form for through wall mounting * 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 Specfic Features * No affected by long period at low humidity values. * Patented solid polymer structure. * High resistance to chemicals. * Fast response time.
