Shannon Hicks replied to the topic Power Issue in the forum Mayfly Data Logger 10 months, 3 weeks ago
It sounds like things aren’t connected to the Mayfly board properly. The 3.7v Lipo battery gets connected to only one of the JST jacks labeled LIPO BATT on the Mayfly board, then a 6v solar panel gets connected to only one of the jacks labeled either SOLAR1 or SOLAR2, and not both. Are you using one of the old style glossy 3.5w panels, or one o…[Read more]

I wrote the same code for all of the Spokane stations. Compare the battery behavior for SpokaneR-SpokaneValley (poor) to that of SpokaneRiver-Peaceful (good), despite running the same code.
I’ll attach the code for both stations.

Mark E. started the topic LTE module and ArduinoHttpClient in the forum Miscellaneous 10 months, 3 weeks ago
I’m connecting to the internet with the LTE Bee module and using the ArduinoHttpClient library to download a configuration file for my logger. The download works fine exactly once. After the first download, it seems like the LTE module “resets” in the sense that prior to the second download reading the signal strength returns 0% and the modem no…[Read more]

@oakleynode wow interesting you are looking at RSSI and it has a lot of variation. I haven’t characterized the RSSI result for a high percentage of failing calls.
Another system that is also on the edge, and I added a new antenna that improved it, the reading is -81dBm https://monitormywatershed.org/sites/TUCA_Mi06/
The modem is a Digi…[Read more]
Pavel started the topic Rain gauge gets stuck in the forum Environmental Sensors 10 months, 3 weeks ago
Hello, I have issues with particular rain gauge. Hopefuly someone has already encountered something like this.
The rain gauge is mechanical “tipping” one, but it does not have two containers for water / two stable states.
It has just one “spoon” which collects water and once it is full it should tip and empty itself and return to default state…[Read more]

I have a station that was recently deployed that cannot maintain sufficient battery voltage. The strange thing is that the voltage drops over one 15 minute increment, rather than gradually over time. Voltage consistently is dropping from the low 4V to the low 3V between successive measurements. Then, at times, the voltage with jump back up to the…[Read more]

@neilh20 – thanks for your very detailed post and information!!
I hadn’t really considered the relationship between connectivity and packet size. I do have some issues at some of my sites with connectivity but always thought about it in terms of local interference. About half of my sites are buoys and someone has suggested to me that the ground…[Read more]

Shannon, thank you. I will keep it at 500 mA, while increasing the solar panel wattage to provide more hours of charging at 500 mA.
