I am having an issue attempting to setup a datalogger to record readings and put the Mayfly to sleep. My setup is an Atlas Scientific EC and temperature probe as I2C protocol connected to an I2C hub. I would like to simultaneously take readings from both of these sensors and save them to the SD card. Meanwhile, have the sensors go to sleep…[Read more]
Thank you @srgdamiano 🙂
I’m sharing some integration test results. I’ve been using a Vbat=4.0V threshold – that is under Vbat=4.0V it does sensor readings only, and stores the readings for later reliable data delivery.
When the battery voltage is over Vbat=4.0V it POSTs the readings to MMW.…[Read more]
The “best” way to work with ModularSensors would be to write the c/h files and submit them as a pull request. 🙂 But if the calculated variable is working, then feel free to keep using it that way for yourself.
If you define your variable for the DS18 temperature as something like
Variable* ds18Temp = <span class="pl-k">new</span>…[Read more]
I have a reasonably basic question about the modular sensors code. We are trialing new arduino type sensors that are not included in the modular sensors library. What is the best way to make these work with the modular sensors logger code? At the moment I am creating ‘calculated’ variables, but I’m hoping there is a tidier way to do th…[Read more]
neilh started the topic Two depth sensors for reliable depth measurement confidence in the forum Mayfly Data Logger 1 week, 2 days ago
I’ve released a Mayfly image that interfaces to two depths sensors – an Insitu LT500 and Keller Acculevel – and pushes the readings to MonitorMyWatershed.org over a Digi LTE CAT-M1 modem.
As a binary image, anybody can download it into a Mayfly, no programming experience needed. https://github.com/neilh10/ms_releases

I’ve had a simple system soak testing.
It has an Xbee WiFi, LiIon 500mA, measuring MayflyVbat and ADS1115 extVbat. When the extVat voltage is >=3.85V it will
and when below <3.85V only
I’ve used the 3.85 threshold as I found the Mayfly was resetting when the WiFi turned on…[Read more]
