Would it be worth it to purchase a new one? Or is there more troubleshooting we could do with the current setup?

We were finally able to get a voltmeter and test the connection. There is voltage being applied to the sensors when the channel scanning sketch is running, but the program still says no sensor detected and to check the physical connection. We have tested both sensors. Could there be an issue with continuity?

We have tried both of them individually and have changed the 3.3v position to the 12v position for the Clarivue sensor. The Hydros is still connected to the 3.3v. We have also changed the sketch for the…[Read more]

Could you detail how to make sure we are supplying the 12v to the ClariVue? That being said I am still a bit confused as to why the Hydros 21 would read as vacant when it is the only sensor connected during testing and it would run regardless of the voltage.

After completing the code (or what I thought was completing the code) and connecting it to MonitorMyWatershed, I am reading -9999 from both the ClariVUE 10 sensor and the Hydros 21. I believe that both are physically connected properly. I think that it might be an issue…[Read more]
