MUNIA belongs to the family of finches and is a small sociable bird with different expressions in plumage and vocalization.

Just like the temperature sensor, the humidity and temperature sensor Munia can be integrated into an existing wireless M-Bus network and provides reliable measurement data. So the air humidity and room temperature can be monitored wirelessly at any time.

Both sensors have the same casing and can be easily mounted on the wall. The configuration can be done at the factory or local via dip switches. The battery life is up to 10 years, depending on the transmission intervals set.
