Batteryless IoT Sensing Node

Students of Indian Institute of Technology Kharagpur, Anandarup Mukherjee, Arijit Roy, Sanku Kumar Roy won the award for developing a prototype of Batteryless IoT Sensing Node. They carried their project work under guidance of Prof. Sudip Misra.

Being a primarily agrarian nation, India still has a large chunk of its population earning their livelihood through agriculture or its associated practices. However, the recent climatic changes are disrupting the time-tested and age-old agricultural practices, which were mainly intuition based or seasonal.

Despite the availability of scientific means of agricultural practices in India, they are not practiced at their full potential due to prohibitive initial costs or high maintenance costs. In our proposed innovation, we specifically are focusing on sensor nodes which are used for monitoring the agricultural field parameters. We have developed a battery-less sensor node which is designed to be placed in the field, without any chance of getting their power supplies replenished. We believe that reducing certain essential components in a sensor-based system, such as the battery, the net cost of each sensor nodes comes down, which in turn makes it more affordable to the masses. As purchasing the almost maintenance-free sensor node is a one-time investment for the farmer, the benefits of the purchase in terms of increased water savings, higher yield, and power savings, far outweigh the initial costs. The only recurring cost to be borne by the farmers is the basic cellular data connectivity for the mobile charger and aggregator node, and minimal subscription charges for using the server-based analytics. Additionally, this approach not only increases the functional lifetime of sensor nodes beyond the typical 1-2 years mark but also makes it much cheaper in the long run. Being a pick-and-place solution, it can be easily operated and handled by people with no prior technical know-how, especially in the rural areas. Link:
