Energy Harvesting

Air Pollution Monitoring Device (APMD) Features:

• APMD is equipped with energy harvesting power management and is powered through solar energy and battery backup
• System measures concentrations of NO2, ozone, CO and SO2, PM2.5 and PM10 using semiconductor sensors. Further, the system gathers other environmental parameters like temperature, humidity.
• Prototype is equipped with a GPS sub-system for accurate geo-tagging
• Learning based smart sensing method – reduce sensing energy consumption

Smart Metering Features:

• System prune the IoT data at the source node by providing some intelligence, thereby aiding to the wireless IoT node’s energy sustainability and efficient channel bandwidth usage for scalable deployment
• Embedded implementation of data-driven dynamic pruning of multi-parameter smart meter data
• Integration with Nb-IoT. Fallback compatibility with Wi-Fi.
• Microcontroller implementation of Multivariate Data Compression Algorithm

Value Proposition

• In APMD, designed PM sensor saves 57% energy compared to the traditional one. APMD is 43% and 99% more power-efficient compared to the reference prototype and  commercially available competitive devices, respectively.
• In Smart Meter, results show that the energy and bandwidth savings with multiple univariate data pruning are respectively about 19% and 36%, whereas the savings with multivariate data pruning are respectively about 36% and 98%. The developed embedded data pruning module is 99:09% more energy efficient than the implementation on Raspberry Pi.
