need help on analog circuitry and sensors

Former Member

Hi,

I'm looking to start a project for monitoring the health of a river. My goal is to set up a system where I can monitor sever points along the water, testing for pH levels and dissolved oxygen levels. I'v been programming for a long time now, but I am new to dealing with analog circuity, and sensors. Does any one have any experience with these (passive) probes and how did you design your analog circuitry?

Thanks

    I'm afraid I can't add anything to help you out here (probably good, since it's a two year old question anyway). But that said, I've been kicking around the idea of building some sort of pool water multi-sensor thing, so I could get an e-mail every morning (for instance) that would report on various levels, including Ph, in the water. I'm not having a whole lot of luck finding sensors though, so I'm curious if and how this project progressed?

     

    Thanks!
