Shannon Hicks replied to the topic Mayfly v1.1 technical questions forum thread in the forum Mayfly Data Logger 2 years, 1 months ago
Mayfly v1.x power usage (with no external sensors attached) and both LED dipswitches off (the brown/white slide switches between the main power switch and the vertical SD card socket) is as follows:
Mayfly current when board is powered and idle: 6.5 mA
Mayfly current when MCU put to sleep and no microSD card in socket: 0.27 mA (or 270 uA)
Mayfly…[Read more]

End device certification for an open source DIY project like this is nearly impossible, since there’s an infinite number of combinations that users can configure their station with various equipment, accessories, antennas, not to mention all the ways they can change the actual code running on the main processor board. That’s why we try to use…[Read more]

@mbarney, do you know if the REVX plan/sim card you had success with is the CATM version (50mb for $5) or the 4G version (10 mb for &12)? With the new modems I have not been able to register on the network (cereg 0,3) using the 4G plan and sim that worked for a couple years with the old xbee modem.
@shicks, RevX systems technical support has…[Read more]

Following from the post @dysumner https://www.envirodiy.org/topic/mayfly-v1-1-technical-questions-forum-thread/#post-17284
I thought I would share some data that I’ve got from running a Mayfly on non-rechargeable Primary Battery outside.
Batteries are electro-chemical reactions and temperature does affect them. I chose 3.6V ‘D’ LiSOCL2 ~ 12Ahr@0C,…[Read more]

Hi @neilh20, I believe the SIM we used was a RevX.

Yes, on all those dependencies. I’ve ordered but haven’t received the Mayfly 1.1. I need to choose the sampling interval and battery mAh for the system so that we can get the most data over the deployment period with plenty of spare power capacity to ensure data collection at the end of deployment, which is the most important.
I have all the mA…[Read more]

We’ve release several different Mayfly Data Logger hardware versions in the past few years, so I’d need to know which version you’re using. I’m assuming a v1.0 or 1.1 since you mentioned deactivating the LEDs using the dip switches. But it also depends on the sampling interval you’re planning to use (time between measurements when the May…[Read more]

I need to calculate the expected power consumption for a 10 month deployment, fully battery powered (no solar). Where can I find specs on the Mayfly power consumption? I realize that it will vary depending on dip switch settings (as Shannon mentioned above), so data to calculate power consumption based on their settings would be amazing.
Thanks – Dawn

I wonder if anybody has looked at using transmission via Swarm.space M138 , https://swarm.space/swarm-m138-modem/
There is a kit available through sparkfun https://www.sparkfun.com/products/19236 $150
and it looks like its going to be fairly low cost annual subscription of $60/month with a tight coupling of 750messages per month. Since its…[Read more]

@mbarney, thanks for the settings. What was the sim supplier that you used – a Verizon direct, or an MNVO like REVX.
I did get an email earlier this week from SimCom that there 7080G was now certified by Verizon, so good to know it works 🙂
