Shannon Hicks replied to the topic Attaching a Campbell Scientific OBS3+ turbidity sensor to Mayfly in the forum Mayfly Data Logger 4 days, 9 hours ago
The OBS sensor comes a with bare-wire cable with 6 leads. Three of them need to be connected to the Mayfly ground (sensor power ground, sensor signal ground, and sensor shield). Then the 3 other sensor wires get connected to the remaining 3 pins of a Grove terminal (note, you have to use one of the two Aux A/D Grove inputs only). Seeedstudio…[Read more]

For each supported sensor in the Modular Library there’s an extensive wiki. I haven’t used that sensor, but the OBS3+ wiki (https://github.com/EnviroDIY/ModularSensors/wiki/Campbell-OBS3) says that it’s an analog communication and here are the wire color details:
“The power supply is connected to the red wire, low range output comes from the blue…[Read more]

Great, thanks for your quick reply. Is there a way to connect the sensor to the board without the screw terminal adapter?
Shannon Hicks replied to the topic Attaching a Campbell Scientific OBS3+ turbidity sensor to Mayfly in the forum Mayfly Data Logger 4 days, 17 hours ago
We currently don’t sell the screw terminal adapter, but I’m working on getting them to Amazon this week. I’ll post an update here when they are available.

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]

You can completely ignore the error “override controls (override/final) only available with -std=c++1 or -std=gnu++11” I’m not sure why it always comes up. I can’t imagine your compiler version isn’t high enough to support it.

Thanks! Bummer about not being able to average out samples over a period of time but I understand the power limitations for a normal mayfly system.
The double logger was going to be my fall back so we can at least save some higher frequency data. I was using the Decagon5TM sensor as an example but was getting an warning on the…[Read more]
