Overview

The LK+ LoRaWAN measures air quality in a duct. Depending on the version it reports CO2, mixed gas (VOC), temperature and relative humidity. It sends its data by LoRaWAN on 868 MHz and also has two analogue outputs of 0 to 10 V or 0 to 5 V, where each output can carry a set mix of CO2 and VOC. It can run from 15 to 35 V DC, 19 to 29 V AC or two AA batteries. An external antenna can be added in radio-shielded locations. Setup is by app, uConfig, jumper or LoRaWAN downlink.
