Hi all
Just wanted to get your thoughts or options for lifepo4 power for monitoring stations. First off, I generally use an arduino pro mini 3.3V for switching on/off the main logging system and in sleep mode the pro mini consumes ~50 uA. I’ve also just got a hold of the rocket stream mini ultra which promises 4 uA sleep current, lets see…[Read more]

I updated the ADC library and changed the ADC definition on line 77 to the 1115 and that did the trick. 1.5V. I am assuming that any past data taken in the field with the wrong ADC definition cannot be back calculated. But moving forward we have a working PAR sensor.
Thank you so much for taking the time to help solve this. Much appreciated.

Sorry I didn’t catch this earlier when I looked at your code. But in line 39, you included the wrong library. All of the various Mayfly board versions we’ve ever built have the ADS1115 chip on them, so you need to specify the ADS1115 library and no the ADS1015 library (because the 1015 is the lower-resolution version of the chip). So line 39 if…[Read more]

Current board that I am working on in the lab is a 0.5b. But we have run into the same issue with logging/calculating PAR using version 1.0 as well. We are running a mix of 0.5 and 1.0 in the field due to many of the older 0.5’s USB ports failing.

Shannon,
Thank you for the explanation on the fees. The Maker Flexible plan sounds good to me. We will just turn off the logger station as you suggest, which we’ll do in November and the keep the card active so that we can redeploy in the spring.
Shannon Hicks replied to the topic Hologram monthly bill in the forum Miscellaneous 1 years, 12 months ago
I think you might be mistaking the monthly fee with the initial $20 auto-pay amount they charge to maintain a positive balance in your prepaid account. The typical plan we recommend is the Maker Flexible plan, which is $0.60 per month (whether you use the card or not) and then $0.40 per MB of actual data usage. Most of our loggers (when t…[Read more]

We have recently set up our first Mayfly system and really love it so far. For the cell phone service we signed up with Hologram and have a monthly bill of $20. Does this sound about right? Has anyone had experience pausing the service while the system is removed for the winter season?

Which hardware version of the Mayfly board are you using this sketch on?
