There are various sensing modalities, e.g. acoustic, seismic, magnetic, Electro-optic, Infrared, temperature, soil moisture, humidity, air quality, rain/wind, chemical, pH value etc. Each sensors have unique merits in measuring subject metrics from its own perspectives.
- Data transmission is expensive and energy hungry, and On-node data analytics helps to compressed data suitable for transmission with low-bit-rate wireless networks.
- Information fusion among networks of IoT sensors provides the overall situation for the areas of interest, and add value to customers.
