RELATIVE HUMIDITY MODULE
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.
