DatasheetProduct: Smart Spot Air Quality & Sound Level Meter

Smart SpotAir Quality & Sound Level MeterSmart Spot is an advanced and robust IoT device that allows monitoring of different environmental parameters such as air quality (gases and PM), temperature, humidity, flow of people (crowd monitoring) and noise. Therefore, a unique monitoring station is offered with a high capacity to obtain data on the context, environment and ambient to know the evolution of a city.The inclusion of all these sensors and capacities in the same device provides savings in the installation, maintenance and management of all sensors, as well as in communications. For the connection possibilities of this device, multiple protocols are supported: Wi-Fi, GSM/GPRS (M2M), LoRa (LPWAN) and 4G/NB-IoT.
