I’ve uploaded one older script to github.com at https://github.com/WEN-Research-Group because this script is getting the data to Google Sheets, and still using the Modular Sensors ecosystem, but the timing is off and it is never entering sleep. It’s just a single file in a repo.

Thank you @neilh20 and @vogelrnws for all of your help! Yeah, based on what I’m seeing, I don’t think its been connecting at all. I have been checking the channel I’m using whenever I’m trying to connect and no data has been popping up in the fields. It’s only got like, 5 fields, so it’s not too complicated either. Sorry, I’m somewhat…[Read more]

The Y511 turbidity sensor with wiper is the most common we use, and everyone is very satisfied with it.

    I’ve been working with a water utility, and after doing a careful comparison with their other…[Read more]

Have you seen this?

    There are really only two ways for you to assess data gaps:

I will definitely be interested in these when they are available.

    @aufdenkampe do you have any feedback about YOSEMITECH turbidity sensors? My questions are:

    1) Are they as reliable as other turbidity sensors, i.e. do they drift more readily, or provide strange values? For $510USD (non-wiper) or $680USD (wiper), they seem…[Read more]

I think I had just figured out the cause of my problem right about the time you were posting them, but needed to continue refining and testing my code before replying.

    What’s working now is:

    1. In the sensor’s setup() function, set trigger pin to an output
    2. at powerUp(), set pin HIGH
    3. at wake(), run the…

I wonder whether it could be the turbidity sensor, rather than the Mayfly, that’s actually drawing power, but I wouldn’t have thought it could do that while (or if) the Mayfly is sleeping. A bit more about my circuit:

    I’m powering the Turner from Mayfly’s switched 3V3. The Turner’s analog output is 0-5V, which…[Read more]

    I had seen that post on the $3 EC meter several months ago and experimented with building a variation of that sensor but had little success.  Thought that it might be better to buy something that already works, to better understand it, an not try to reinvent the wheel.

    I would love to see what you come up with for…[Read more]

So, it never tried for longer than 15 minutes with that sketch because the watchdog doesn’t get “fed” while it’s waiting for the internet and it “bites” (ie, forces the board to reset) after 15 minutes. But 15 minutes is still a pretty long time to wait.

    After the first connection in a new location, it should connect much faster in…[Read more]

It seems to be working but I need to calibrate etc. I haven’t seen this…[Read more]
