andrew3000 started the topic LiFePo batteries or other battery recommendations in the forum Infrastructure and Equipment 1 year, 5 months ago
Has anyone tried hooking up Lithium Iron Phosphate batteries to the mayfly boards? I am wondering if the built in charge controller would be compatible with this chemistry.
Any other recommendations for batteries would be greatly appreciated as well!

Hey Ryan,
A UCB student ran research group I founded called the Strawberry Creek Monitoring Group will be transitioning to a decentralized LoRaWan network called helium networks using mayfly boards. They will be starting work on this in the next few months. We can keep you up to date on our progress if you like! Also, we already built a alarm…[Read more]

We have been testing out the Turner C-FLUOR (PC) PHYCOCYANIN sensor and getting mixed results where we are not sure if it is the sensor, sketch, or something else.
When measuring pure di water we are getting readings of around 5 – 6 ppb in both an opaque jar and open jar with the sensor in a shade cap.
We bought blue spirulina (…[Read more]

Hello Shannon,
I am with Digi International – I wanted to check in to see if you were able to get our new XBee modules working on the Mayfly. If you need more information, I can connect you with Tech Support or an FAE who can provide any information you need.
We’re excited to see this XBee application, and we appreciate you working with our products!

Ryan NoCO started the topic Replace logger cable with LoRa? in the forum Infrastructure and Equipment 1 year, 5 months ago
Hi, I’m curious if there are any plans to replace the data cable from sensor to the MayFly with LoRa wireless technology or to make it an option? LoRa (Long Range) is a wireless communication technology, specifically a physical (PHY) layer protocol, designed for long-range, low-power, and low-data-rate communications, primarily used in Internet of…[Read more]

Shannon Hicks replied to the topic Pelican 1120 drilling template in the forum Mayfly Data Logger 1 year, 5 months ago
I haven’t seen any other templates besides the one you linked. I never use them myself, I just lay them out in whatever pattern is the easiest, based on the sizes of the cable glands. I prefer to stagger them as shown in this photo from the kit’s shop page, since that makes it easier to get your hand around the end part to tighten them. I us…[Read more]

Can someone direct me to a 4 hole drilling template if it exist?
I found this: https://github.com/EnviroDIY/EnviroDIY_Mayfly_Logger/blob/master/hardware/1120Pelican_enviroDIY_5.pdf
I thought I found and bookmarked a 3 hole version before, but now I can’t seem to locate it.
Thank You
