This may have been asked already.
The Mayfly v1.1 board. What is the temperature range that this board can stand for a closed up box? Also, we have the 4400mAh LIPO battery, Operating and charging with the solar panel. What is the min and max temperatures can this battery stand with a closed up box?
Thanks,
Rogers

Thank you so much, Shannon!

@jamesbailey I’ll check with my colleague to find out exactly which SIM he used for the test; he’s in the field for a few days. My test code is based on https://github.com/EnviroDIY/ModularSensors/blob/master/examples/DRWI_SIM7080LTE/DRWI_SIM7080LTE.ino, and the only modem-related code change I made was to the APN.

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)

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]
