EasySens® Sensors


Energy-harvesting wireless duct sensor for the measurement of temperature in gaseous media of heating, ventilation and air-coditioning systems. The SR65 AKF can be configured via airConfig software to customized measurement ranges, transmission intervals and wake-up times. When used in dark places, a backup battery can be inserted.
