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 e…[Read more]

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…[Read more]

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…[Read more]

I have recently put two Mayflys with OBS3+ turbidity sensors out in the field and they are not reading correctly when confirmed with a handheld nephelometer. The low readout is reading too low and the high is reading too high. I’ve triple checked my code and the calibration curves are correct. Does anyone have any idea why this is happening? I…[Read more]

Has anyone used the Atlas Scientific industrial pH probe with the Mayfly? I’m looking to deploy a pH sensor in a small tributary. I would love to hear about your experience with it.

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

I have successfully deployed two stations with Meter ES-2 sensors. I’m trying to put together a third station with and ES-2 sensor and a Campbell Scientific OBS-3 turbidity sensor, but I can’t figure out how to attach the OBS3+ sensor to the Mayfly board. The manual says to use an “EnviroDIY six-port screw terminal-to-Grove adapter board”, but…[Read more]
