      I uploaded the “SDI12/b_address_change” sketch and the address of the sensor is correctly assigned at “2”. My sketch is below. I modified the DWRI CitSci code for the ClariVUE. Thanks for taking a look!

        I used the Mayfly 1.1 board and the sketch below. Thank you for helping me!

          Thank you for the response Shannon. I stripped and tinned the wires on the sensor, connected it to the 6-pin screw terminal as directed, connected the screw terminal with a grove cable to a SD-12 port on a Mayfly 1.1 board with the jumper moved to the 12v position. I also changed the sensor address to “2”.   For some reason, I am getting an error reading of -9999, which I think means that my sensor isn’t getting power. I used the code in the menu a la carte example on github. I think the D22 pin is set to high in that example. Does anyone know what  I could be doing wrong?

            Hello, I have a few Mayfly dataloggers deployed with Campbell Scientific OBS3+ sensors. I recently purchased a Campbell Scientific ClariVUE10 sensor and a Mayfly 1.1 datalogger and am looking for some advice.  I noticed that the new ClariVUE10 has only 4 wires (OBS 3+ has 6). Can I use the EnviroDIY Multipurpose 6-pin screw terminal to attach the new sensor to the board or do I need to purchase something else?

            If I can use the 6-pin, which wires plug into which screw terminals? White is SDI-12 data, red is 12V power, clear is shield and black is ground.

            Thanks!

              It turns out that I had had wires of the OBS3+ in the wrong screw terminals. Rewiring the high and low turbidity readings within a reasonable range. The problem now is that the sensor is not reading accurately. High turbidity always reads about 3 NTU and low turbidity always reads about 1 NTU. I have measured with two handheald turbidity meters and they were both reading 11-12 NTU. I checked and the grove cable is connected to the AA0-AA1 terminal and the aux analog port is switched from 3V – 5V. I’ve attached a photo of my wiring. Thanks!

                Great, thanks for your quick reply. Is there a way to connect the sensor to the board without the screw terminal adapter?
