Flex-Sky-T-RH – Nokeval

Flex-Sky-T-RH transmitter

The Flex-Sky-T-RH measures the ambient temperature with a built-in Pt100 sensor plus the ambient relative humidity in the environment. This sensor is typically used for indoor air quality measurements and the relative humidity conditions in indoor rooms.

The Flex-Sky-T transmitter consist of a radio part (antenna) and a measurement part. The measurement part can be recalibrated or exchanged with a fresh recalibrated one without significant break in the measurement. The wireless system is connected with each other through the LoRa signal, this is an advanced modulation technique that achieves much wider wireless ranges than the traditional techniques. The Nokeval Sky product family uses this technology at the license-free 433 MHZ ISM band (in Europe fully accessible). The battery powered 10 MW transmitters have an open-space range of more than 10 kilometres and the practical range is several kilometres in most outdoor applications. The modulation technique tolerates other traffic on the same band very well.
