When you did the address changing sketch, did you get a positive result using the serial monitor that showed the channel was changed to something other than 1? Sometimes there’s a glitch where you have to set the channel twice before the change actually happens and it stays on the new channel.
What sketch are you using for the logging sketch…[Read more]

We tried that but are still getting -9999 values.
Shannon Hicks replied to the topic Hydros21 sensors not returning data in the forum Mayfly Data Logger 2 years, 1 month ago
Did you do the example “b_address_change” sketch first, to change the sensor’s default channel from 0 to 1?

We are unable to get our Hydros 21 CTD sensor to return data. We are getting -9999 values on both the SD card and the website. All the connections are secure. The SDI-12 address is set as follows:
<div>
<div> const char* hydrosSDI12address = “1”; // The SDI-12 Address of the Hydros 21</div>
<div> const uint8_t hydrosN…[Read more]

Hey Brian,
Yay! Glad to hear! I can email you the website link and login credentials.

What’s the name of your site? Right now it’s only set up to run on meter hydros 21 sensors but i should be able to add some new ones pretty quick. Also what is the location of the site/name of the town you plan on using for incorporating…[Read more]

@brianjastram I just launched a webapp for this and I am looking for people to use the system and give me feed back. Here is a post with some more info, LMK what you think. https://www.envirodiy.org/topic/free-alarm-system-for-monitormywatershed-updated/

I recently launched an alarm system webapp built on top of monitor my watershed to enable email alerts based on both sensor values and local weather forecasts. Is interested in testing it out and giving me feedback? No downloads or programming needed.
Here is a demonstration video! I will be releasing the source code likely by the end of this…[Read more]

They are actually Turner Designs Cyclops-7F sensors that we use for measuring chlorophyll and phycocyanin (https://www.turnerdesigns.com/cyclops-7f-submersible-fluorometer). They are supported by the ModularSensors library and there’s more information about them here: https://envirodiy.github.io/ModularSensors/group__sensor__cyclops.html
