bettair MK2 Urban Air Quality IoT Sensor Node

bettair MK2 is a fixed sensor node placed on a street light or urban furniture. It measures the gases NO2, NO, SO2, CO, O3, H2S and CO2, the particulates PM1, PM2.5 and PM10, as well as noise, temperature, relative humidity and pressure. The aim is to achieve fine spatial and temporal resolution with a dense grid instead of a small number of expensive stations.

MK2 features

• IP65 housing, special low-power electronics.
• 3G/LTE/4G, 5G, NB-IoT, LoRaWAN or wired Ethernet connection.
• No field calibration required; post-processing based on unsupervised machine learning is applied to raw gas sensor data, and the manufacturer states that Pearson correlation with reference stations is above 90%.
• The cloud platform shows each node's instantaneous status, heat maps by pollutant and a common air quality index.

Municipalities and environmental agencies use this data to monitor pollution hot spots, sources and the effect of reduction strategies; odor and noise mapping can also be done.

Choosing MK2

Which gases are monitored is determined by the purpose of the network; NO2 and particulates stand out for traffic-related pollution, and SO2 and H2S in industrial zones. In a dense network, instruments complement each other and source identification becomes easier.

Tetra plans node placement and communication method according to the city's infrastructure, and carries out installation and connection tests. Platform access, field replacements and spare parts are within the scope of support.
