Hey @Mquist, Thanks for the interest in my project. I really wish I had my website/documentation completed as it could be super useful to you. I’ll do my best to answer your questions and if you have anything additional, feel free to continue posting or send me a private message.
First off, the graph above is the output from the fuel.SoC() function. This reading is taken every 15 minutes for 49 days continuously. (except when webhooks have not been working properly). The percentage is the state of the charge for the 3.7V 6600mAh Lipo battery. That maximum value I’ve gotten from this function is 91.488%. I still have to do some of my own tests to see how accurate this value is. I just received an additional supply of Electrons, so I will be testing that shortly.
My setup is for a Rain Gauge, which measure precipitation. The Electron is in a waterproof housing which is contained within the Rain Gauge we designed. We’re using waterproof RJ45 Connectors made by CONEC to communicate with our I2C Differential Pressure Transducer (1PSI). I also designed a simplistic PCB (printed Circuit Board) for the Solar panel/I2C connection.
As for data usage, you’re in luck. I just requested that information from Particle. See the image below:
If you would like to see the time intervals, I’d be happy to share the CSV data file with you. I forget the exact amount of time my code sketch takes to run, but its somewhere between 5-10second. The Electron sleeps for 15 minutes and wakes up to take a reading from the pressure sensor. As we add more nodes, I may have my server message each device every fifteen minutes to wake up and read. I know this is possible, but it’s something that hasn’t transcended the idea phase yet.
Unfortunately, I do not have any specific measurements for power consumption. Once we conduct more lab testing I will have a better idea. Our data is coming from a proof of concept which is in the field some distance away from us. As I work on updating the firmware/ building out our website/server I can share more detailed documentation if you’re interested.
Best of luck!
