Thank you for the information.  We will try that and see if we can get it working right, otherwise we will get a new switch.

Have a good day.

I have been looking to redeploy my Mayfly v0.5b dataloggers here this spring, but one of them has been having issues with the power switch.  Originally, the Mayfly would work for a few days but then would stop suddenly.  Now, when the switch is turned on, the lights that we have turn on to show when the Mayfly is sending out a signal r…[Read more]

Thank you everyone for your help. These issues have been resolved.

Thank you for the information. I removed the unnecessary parts in my code, as we currently were not using the OLED screen. Since we are not using the screen any longer, I2C is also no longer being used. All switches on the two boards that were not working as well as the boards in the field are where they need to be, so that is likely…[Read more]

I had deployed several Mayfly loggers last week to collect data from a turbidity sensor, and they would log data to the SD card in the lab and for a short time in the field but at some random point they stop logging. Some would log for a few hours while others would log for a few days before stopping. The Mayflys were still running, as…[Read more]

Thank you for the quick reply and the information. This was exactly what we were looking for, and now we are getting the data that we need. Thank you for your help.

I am trying to read a voltage from a low-cost turbidity sensor, and log that to an SD Card. It is set as a float value (it is <float turbvoltage> in the code below, about 43 lines down when counting spaces), so only outputs to two decimal places when logging to the SD Card (near the end of the code string). I would like to get it to…[Read more]
