Thanks Shannon. Could you share the logic converter you have had success with? I like to give another logic converter a shot.

We’ve used a Mayfly successfully with a variety of SDI-12 sensors from different manufacturers, including ones that require 9v or 12v excitation. I usually use a custom simple logic level converter with most of them, similar to the Sparkfun item Greg mentioned above. However the only ones that gave us problems were the YSI 6-series sondes, so I…[Read more]

Greg,

We never revisited the issue and instead just gave the address to the CS-215 via a CS logger. I know that our team installed an ATMOS-14 at the site, and got around power issues by just powering the sensors separately from the Mayfly board by using DIN rails. It really seems that the different power requirements between the board and the…[Read more]

Oops. Sorry. I’d typed that and didn’t see your response. But yes, slowing down the ESP8266 is the way to go if you want to make sure everything is heard correctly.

Sara Damiano replied to the topic ESP8266 in the forum Mayfly Data Logger 4 days, 16 hours ago

Yes, I’ve had problems with the Mayfly receiving data at 115200. The Mayfly is only running at 8MHz and Atmel says the error rate at that baud and crystal combination is 8.5%. The error is a much bigger problem on the receiving end than the sending end. So the serial port monitor and the ESP8266 understand what the Mayfly is saying at 115200,…[Read more]
