Rainwater harvesting gets ‘smart’

Automated process of water storage through wi-fi mounted microcontroller

The students from ‘Team LinkLer’ at the National Institute of Technology Andhra Pradesh (NIT-AP) have developed a ‘Wi-Fi mounted microcontroller’ that can integrate sensors for smart harvesting of rainwater. They aim to address water shortage in Indian cities by deploying technology such as internet of things (IoT) and machine learning. The team developed an end-to-end software stack that provides an easy interface to manage and control in-house water resources.

The system monitors wastewater and supply systems such as rainfall recorded, water remaining in the storage tank, water quality index and water supply in a given area.

The NIT-AP students have also designed an underground storage tank with a material capable of holding the water on a long-term basis and its treatment process being monitored on a feedback IoT system.

This project came from Dr APJ Abdul Kalam’s ‘Open Innovation Lab’ at NIT Andhra Pradesh.
