SR04 x

Energy-harvesting room operating unit for integrated measurement of temperature and relative humidity (rH version) in residential and office spaces. Also available with rotary switch for fan level adjustment, slide switch (for example, "Day/Night") or occupancy button. The device is mounted via adhesive pad or screws and sends its values unidirectionally to corresponding receivers or gateways, which process the information directly or – depending on the application – forward it to a central control unit.
