Some LiPo batteries have the JST connector reversed and that may be your problem. Check the battery with a VOM to make sure the red wire is + and black is –

Hi all,
I’m new to the Mayfly Data Logger boards although I have used a couple of Arduino Unos. Today, I was set-up a water temperature sensor for a project me and my team have coming up. I was able to get the senor up and running but as I was put in the finishing touches(adding the solar panel and the lipo battery), I could smell the board…[Read more]

Hi Shannon,
We’re working with Atlas Scientific sensors. Our final set up will include three sensors – pH/temperature, dissolved oxygen, and conductivity.

We’ve installed several stations in tidal areas by attaching the sensor to a custom apparatus mounted to docks or piers. What kind of sensors are you planning to install?

Hi All,
We are in an area that experiences a 5-6 foot tidal range, and many of our sites are composed of salt marsh with soft, muddy substrate. Has anyone had any issues using the suggested rebar installation in this type of environment? I’d like to avoid the possibility of sediment burying our sensor setup and was curious if anyone had more…[Read more]

Matt Barney replied to the topic Code change for Meter Hydros 21 CTD in the forum Mayfly Data Logger 2 years, 3 months ago
A couple bits of additional info. To visually identify whether your Hydros 21 is a Gen 1 or a Gen 2, see attached photos of the sensor head on each version. Note that some Gen 1’s had red cables, but not all.
Second, as Shannon noted in the post she linked to above, the address-setting on the Gen 2 is slightly more finicky; you just have to…[Read more]

Yes, the update made to the ModularSensors code in in order to fix Hydros 21 is backwards compatible. I mentioned it last week in this post: https://www.envirodiy.org/topic/hydros-21-decagon-ctd-reading-error/#post-17066
It seems that in the past year Meter Group made some changes to the amount of time the CTD sensors need to take a…[Read more]

Does the new setting still work with the older sensors? Do we need to maintain 2 sets of code? Thx.
