Scott Murrison replied to the topic Mayfly and Maxbotix MB7386 Range Issue in the forum Mayfly Data Logger 1 week, 2 days ago

I thought about that too. I’m not sure if there is a way to check. The model number says it is supposed to be a 10 meter sensor. And the reading shows 9999 when the object is out of range. This is typical of the 10 meter models. I believe the 5 meter models show 4999 when out of range. Maxbotix isn’t sure what the problem is. They sent me…[Read more]

Any chance it’s the 5 meter model? From what I’ve seen it’s not possible to tell the difference from the housing. (I’d love to be corrected and learn how to tell if I have that wrong.)

Hello all,

I am still trying to get a water level sensor together. I got the code, radios, and Ethernet connection all working. I am able to get the data posted to a MySQL database. Now I am having range issues. The MB7386 should detect objects about 30 feet away. The most I am able to get is 15 feet to a cinder block wall. I am using the…[Read more]

I’m sorry, I just looked back at your link from the first page and they mentioned they were using a Mega, which should be 5V. I don’t know. I don’t have any other guesses. Do you have an oscilloscope you can put on the line to watch the communication between the sensor and CR1000? If so, can you share the results of sending a single command to…[Read more]

Hm. I doubt the mid-character times are the problem, but it is possible that the break or marking times are causing problems. You can try tweaking them a bit on the very top of the SDI12.cpp file.

Instead of timing, it’s possible there’s a voltage problem. Do you have the sdi-12 data pin going directly to the Mayfly? Then the power and ground to…[Read more]

Hi Sara,

We spent several hours today trying to work with the CS-215. We did update and use the most recent library (1.3.1) but were still having issues with the two examples. For the address change example, all of the addresses were vacant, even though we had defined the sensor having an address previously using a CR1000 (Campbell) logger. The…[Read more]

Hi Sara,

Thank you for getting back to me. I’ll check the version of the library we have and will capture the serial output. We won’t be having a lab meeting until Tuesday so I will send it right after that. I noticed that there were updates last month so perhaps that will sort things out. In the meantime, thank you for helping!

Thank you Beth and Sara. We are currently using older code to simply wake up the Mayfly, take data, and write to an SD card. This has been deployed outdoors and works. I see the best way to implement the cell phone telemetry is to use code based on “logging_to_EnviroDIY” and the associated libraries. I have only had a chance to download this code…[Read more]

This first version had no cord grips. The students used silicone sealant but water was able to seep in somewhere. They say it didn’t flood. I have since purchased cord grips, https://www.newark.com/jacob/50007m12pasw-f/cable-clamp-gland-polyamide-thrd/dp/15M6172?ost=1168781&ddkey=http%3Aen-US%2FElement14_US%2Fsearch.

While it’s true that there’s no “testing mode” at data.envirodiy, I do test the communication before I deploy by just setting the station up and let it start running. My last test ran for just over 2 days and one station died at 1.5 days because I didn’t have a powerful-enough battery. I was grateful to have it running for long enough to tell. I’m…[Read more]
