  • The Problem:

    Automated data loggers currently available cost more than $ 4000

  • The Goal: To Build the same within INR 4000 ($ 100)

Project status l.jpg
Project Status

  • We have built a prototype

  • Further refinement is needed, primarily in terms of design

  • We aim to build a kit, so that schools can build these loggers themselves

  • Problem: Farmers have begun to use plastic lining for their farm tanks, to minimize water losses

  • These bodies of water attract stray animals, especially during the dry season

  • Dogs dig under the fencing to try and reach the water

Our solution l.jpg
Our Solution

  • A simple device that will be mounted on the tank fence

  • Emits ultrasonic waves at frequencies that dogs find very disturbing

  • Trials are on to determine the right frequencies
