Kombi-Sky-RHT-CO2-TVOC-DP

Kombi-Sky-RHT-CO2-TVOC-DP is a wireless multi-sensor transmitter for measuring indoor air quality.
Kombi-Sky measures temperature, humidity, carbon dioxide content, total volatile organic compounds (TVOC) and pressure difference.

Kombi-Sky uses Semtech LoRa technology, which enables a very long range for a battery powered device.

The device is not compatible with the LoRaWAN infrastructure. If you want to use LoRaWAN technology, select Kombi-LWEU instead of Kombi-Sky.
