7 years ago I tested the new GetValues.ino on all three of my sensors, purchased in April 2017:
- Y511 Turbidity with brush
- Y514 Chlorophyl with brush
- Y520 Conductivity
Good news is that all give believable values and the brushes (for Y511 & Y514) activate with the "Activate Brush" command. The bad news is that for both Y511 & Y514, none of the other functions work.
I played around with the "Waiting for sensor and adapter to be ready" delay (line 77 in sketch). Increasing from the original 0.5 sec to 1.3 sec was necessary to get Y520 to work, as expected, but increasing up to 50 sec had no affect on getting responses for Y511 & Y514. See example output below.
Note 1: The sketch returns a "Failed to activate brush!" error, but the brush actually does move exactly when the "Activating brush" command writes to the serial monitor.
Note 2: For Y514 their appears to be a ~10 sec delay from the first result value before a real value is transmitted. Because that chlorophyl sensor emits a blue light each time a measurement is made, it's clear to see that no lights are emitting in this time. I'm wondering if there is some kind of automatic delay after a brush is activated.
@SRGDamia1, any ideas?

Old sensors versions, including those that Sara has, did not support "Activate Brush", "Get Brush Interval", "Set Brush Interval" commands.
In the old sensor versions, the brush spins 3x one way and 1x the other way, as soon as the sensor gets power. It takes 10-11 sec to do. It will repeat every 30 minutes.
In the new sensor versions, the brush does not spin when the sensor is powered.
Look at code and notes in Get Values example sketch.
