Description

A good sensor arrangement (apart from the Ultrasonic sensor currently used) that can measure the level or volume of the waste accumulated in the vat.

  • The existing problem with ultrasonic sensor: It is a cheap and beginner-friendly solution but it may get affected by waste content splashing on the sensor itself.
  • Here are some constraints that are expected to be followed:
  1. The choice should be economic
  2. It is okay to penalize a bit of accuracy for reliability/robustness
  3. The sensor should be easy to implement (readily available solution or a custom solution that doesn't involve much production complexity)
  4. Immune to splashes, fluctuating light intensity, or other interferences

Contributor guide

Research direction
Research alternative sensor technologies for waste level measurement. Consider constraints: cost, robustness to splashes and light interference, ease of implementation. Compare options like load cells, IR distance sensors, laser rangefinders, and capacitive sensors. Provide recommendations with trade offs.
