Shannon Hicks replied to the topic Mayfly v1.1 technical questions forum thread in the forum Mayfly Data Logger 1 years, 7 months ago
The sensor manufacturer has assured me that the sensors will work at 3.3v, and we’ve had experience with hundreds of them and concur, but they’ll also work just fine with the jumper set to 5v instead, so it’s your choice.
This thread is for overall technical questions about the hardware on the Mayfly v1.1 boards, so if you have other questions…[Read more]

@shannon I noticed that the specs for the Hydros 21 indicate 4.0 volts minimum. The junper on the Mayfly board is set for 3.3 V. Would you recomend changeing that to 5.0 Volts?

Thanks! I’ll plug that into my code.

@w3asa Did you look at this example: https://github.com/EnviroDIY/ModularSensors/tree/master/examples/DRWI_Mayfly1. I think it’s almost exactly what you want.

@shannon I am setting up a new sensor station using the hydros 21 (due in tommorow) but I am not using the turbidity sensor. I deleted that section of the code but I wanted to add the humidity sensor. What do I need to put in the variable list? Here is what I have:
Variable* variableList[] = {
new MeterHydros21_Cond(&hydros),
new Me…[Read more]
Shannon Hicks replied to the topic 1.1 revB and Clarivue 10 Turbidity Sensor in the forum Mayfly Data Logger 1 years, 7 months ago
The Mayfly makes 3.3v, 5v, or 12v, as set by the jumpers on the headers next to each Grove socket. The ClariVue sensors need 9 or 12v, but at lower temperatures (below 5C) we’ve found that some of the sensor will stop working because the Mayfly can’t produce enough current at 12v at low temperatures. So to fix this issue, you can just change t…[Read more]

To close the jumper on the Mayfly, you need a soldering iron. If you don’t have access to one of those, you might need to go back to the trinket.
You could also order a replacement pendant logger from Onset: https://www.onsetcomp.com/products/data-loggers/ua-003-64

Hello,
I have some questions on the functionality of the board with the Clarivue 10 Turbidity sensor. There have been some threads and posts that the 1.1 RevB boards can power the sensor and take readings, but when trying to use the sensor, I have been getting a reading of -9999.
I am using the six-screw terminal block for the bare wires, and a…[Read more]

@ldecicco, last autumn I started working on a somewhat similar task using the same radio module, but for posting to Azure EventHub.
As @srgdamiano mentioned, the key is to add HTTPS capabilities using the <span class=”lang:default decode:true crayon-inline “>TinyGsmClientSecure client(modem)</span> . Doing that worked for me and I was able to…[Read more]
