Thanks Sara,

I have been working with Bobby and Andy Wickert over there on this and they gave me sensors with the appropriate firmware installed already. I did not have to install any firmware. It was just suppose to be hooked up and ready to work. I didn’t know if anyone in the community here was able to get a walrus sensor to work on the…[Read more]

Bobby Shultz or Northern Widget did some of the work to incorporate the MPL115A into ModularSensors, but I haven’t followed what they’ve been doing.

It looks like this Walrus thing has an on-board processor that in between the Mayfly and the MPL115A.   So you need to use whatever protocol they’ve developed for themselves not the MPL’s I2C…[Read more]

Thanks for troubleshooting the code. Looking at it more…It works with one sensor but not with both on the same I2C hub. It seems that there is a problem when both grounds are connected to the hub with the sleep/RTC pin. I have tried multiple hubs/cables to no avail. Starting to think it is a conflict with one of the sleep functions/libraries…[Read more]

I just compiled and ran your code on my own Mayfly board (replacing the Loop function with the one I edited above), and commenting out anything relate to the Atlas sensors since I don’t have any here for testing, and the Mayfly board slept properly, woke up every minute and took a “sample”, wrote data to the card, and went back to sleep.

If you…[Read more]

It is sleeping all the time and not waking. No data is being saved or printed to the serial terminal.

Is the board sleeping all the time and not waking? Or is it awake all the time and not sleeping? Is data being saved to the card or printed to the serial terminal?

Thanks! I worked through a couple of things, including your suggestions, and I still can’t get the logger to wake up… I know the switch works because if I set it to HIGH in the setup the board does come on and the sensors read/turn on without the sleep functions (and the RTC is functioning/correct). Do I need to have a wakeup function or…[Read more]

It looks like this code was based on one of our old sleeping Mayfly logger example sketches, but there’s some stuff in the main Loop that is out of order. I’m assuming you’ve got the Atlas sensors connected to the I2C Grove port on the Mayfly. If you want to be able to switch their power on and off, then you need to move the small jumper on the…[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]
