Each sensor node can transmit sensor readings directly to the Cloud via GPRS/3G, WiFi or LoraWAN connections. In the case of several nodes located in the same zone, an intermediate Gateway can be employed for collecting data and connecting to the Internet through different options. In case connectivity fails, data can be stored in an internal data base.
The GAIA platform integrates more than 50 different sensors, adapting to any scenario such as air and water pollution, smart cities, security and industrial control, agriculture monitoring, etc. Sensing modules include:
- Environment: Carbon Monoxide (CO), Carbon Dioxide (CO2), Oxygen (O2), Ozone (O3), Nitric Oxide (NO), Nitric Dioxide (NO2), Sulfur Dioxide (SO2), Ammonia (NH3), Methane (CH4), Molecular Hydrogen (H2), Hydrogen Sulfide (H2S), Hydrogen Chloride (HCl), Hydrogen Cyanide (HCN), Phosphine (PH3), Ethylene Oxide (ETO), Chlorine (Cl2), Particle Matter (PM1 / PM2.5 / PM10) , Temperature, Humidity, Pressure
- Water: pH, Oxidation-Reduction Potential (ORP), Dissolved Oxygen (DO), Conductivity, Temperature, Turbidity, Fluoride (F-), Calcium (Ca2+), Nitrate (NO3-), Chloride (Cl-), Lead (Pb2+), Iodide (I-), Cupric (Cu2+), Bromide (Br-), Silver (Ag+), Fluoroborate (BF4-)
- Agriculture: Soil moisture, Soil temperature, Leaf wetness, Solar radiation, Atmospheric pressure, Stem diameter, Anemometer, Wind vane, Pluviometer, Ambient temperature, Humidity
- Ambient Control: Ultrasounds (distance measurement), Noise, Presence, Hall effect, Water presence, Liquid level, Liquid flow, Temperature, Humidity, Luminosity
