BrianJastram started the topic Slow Loading for MMW Pages in the forum Monitor My Watershed 5 months ago
Is there a reason it sometimes takes so long for MMW site pages to load? Just navigating from one site to another or from a site page back to My Sites can take around 1 minute.
Shannon Hicks replied to the topic Sensor Values Unrealistic and Unchanging in the forum Environmental Sensors 5 months, 1 weeks ago
Sensor values of -9999 for the Hyrdos21 CTD sensor mean that the Mayfly board isn’t hearing any communication from the sensor. Did you carefully follow all the directions in the Monitoring Station Manual (specifically section 6) for preparing and programming a Mayfly for use with the Hydros21? The sensor’s default SDI12 channel number needs to b…[Read more]

Hello,
Before installing my system outdoors, I ran a test with my sensors. However, the data I received did not change over the logging interval and seem highly incorrect to me. I have attached a screenshot from Monitor my Watershed on this post. Please let me know if you know of any ways that could help me to fix this issue.
Thank you so much…[Read more]

Neil, thanks for your input. My background is in stream ecology and the engineering students I have been working with are providing the technological expertise that I certainly don’t have. I know the students have […]

Thanks so much for the posting. Fascinating. While R.Pi might be great for prototyping – it does require a lot of mW power, and it can’t be put to sleep. A great way of reducing total deployment costs is to have […]

Michael Daniel replied to the topic Atlas Scientific Dissolved Oxygen Sensor Not Reading in the forum Environmental Sensors 5 months, 2 weeks ago
I have both a pH and a DO sensor working on one of my data loggers., and I’ve had up to four Atlas Scientific sensors working at once using a sensor bridge: https://atlas-scientific.com/carrier-boards/sensor-bridge/ I currently have the sensors connected through the qwiic ports, and they seem to be working fine. Here’s my code, there’s a lot of…[Read more]
fisherba started the topic Communicate between Mayfly and ISCO 3700 in the forum Environmental Sensors 5 months, 3 weeks ago
I am aware of the existing trigger for ISCO 3700, that requires an external sensor to trigger the ISCO, both via a Mayfly. https://github.com/EnviroDIY/Trigger
I’m curious if folks have developed a way for the 3700 to notify the Mayfly that it has sampled, with sampling coming from either using the Liquid Level Actuator or an external sensor as…[Read more]
