Need Suggestion for Sensor Selection

Hi, I’m Salman.

Part of Hardware community called MakerGram. Recently I’ve been part of a hackathon as a mentor. The hackathon held in Kerala, INDIA, you can read the full story from here:

After the hackathon, we realize that this product has potential and we want to build the solution and spread the world.

The solution is to build a river monitoring system to predict flood and river water quality, we completed the prototype using Arduino with some basic sensors, next we need to build stable MVP.

We are a team of different age group and background and located in differt parts of kerala . After discussion with teamwe concluded network as a cellar and next thing select the best accurate, less expensive sensor.

Sensor parameters are :

-> Water level (High Priority )

-> Water Quality

-> River Flowmeter

-> Rain Gauge

Discussion log:

Looking for your valuable suggestion on the sensor selection and feedback. Thank you.

We (Our Sci) don’t do a lot of that, but I would ping this up to @shicks at DIYEnviro (who may be busy and can’t respond, but just in case) who feels like a person who could provide lots of thoughts + advice here.

Thank You , It will help a lot.
