HM1520LF Humidity Transducer
Brand: American Sensor Technologies IncBased 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.
