The UMS2205 system is a high-performance environmental measurement system of the latest generation for long-term use. A wide range of sensors is available, enabling almost seamless environmental monitoring: A certified fine dust sensor that accurately detects particles in the sizes 1µm, 2.5µm, 4µm and 10µm. Sensors for nitrogen oxides, ozone, air quality, carbon dioxide (CO2) and relative humidity to record comprehensive environmental data. Additional measurement options such as the dew point and temperature provide further insights into the ambient conditions. Expansion options for ground temperature, frost detection, solar radiation, brightness (day/night detection), rain, wind direction and speed offer flexible adaptation to different environmental conditions Up to 15 sensors can be installed in the UMS2205 on 5 sensor measuring stations as required. The sensor values are transmitted via two long-range wireless data systems, LoRaWAN and NB-IoT. Live data can be read out via the WLAN interface and configured and updates imported via the web server. The UMS2205 can be expanded fully automatically by up to 30 additional external sensors via Industrial 1-Wire Bus and Auto-E-Connect Plug and Play system. The ESERA Auto-E-Connect system is an extension of the 1-Wire bus standard and has been registered as a German and European patent by ESERA GmbH. Each of the maximum 30 additional sensors can supply up to 5 data values. This means that the UMS2205 can supply up to 200 sensor data to your control system. HIGHLIGHTS WLAN, web server and access point for configuration, debugging, maintenance and firmware updates LoRaWAN, NB-IoT (LTE) long-range data interfaces Connection option for 5 measuring modules with up to 15 sensors, expandable via the plug-and-play interface for up to 30 additional sensors Robust, energy-saving industrial design in a compact and elegant housing (insect-proof, "ball-proof", integrated vandalism sensor) Optional equipment UPS function via battery for at least 10 minutes of operation. Power failures are detected and reported and the sensor data can still be sent to the higher-level control system. Long-term data logger function can be integrated for measured value recording or logging Vandalism protection for the detection of housing openings External antenna for the radio data and WLAN interfaces possible
