RELATIVE HUMIDITY MODULE
HM1520
Based on the rugged HS1101 humidity sensor, HM1520 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. 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 chemicals. Fast response time.
