LA+ LoRaWAN

Air quality sensor for measuring CO2, mixed gas (VOC), optionally temperature and humidity outdoors and in areas requiring high IP protection class (e.g. underground stations, tunnels, exhibition halls, cold chains and greenhouses as well as in production halls and warehouses). In addition to LoRaWAN®, additional analog voltage outputs are available as interfaces. In radio-shielded mounting locations, an optional external antenna can be used to optimize the radio link between the device and the gateway.
