Shannon Hicks replied to the topic Atlas Scientific Dissolved Oxygen Sensor Not Reading in the forum Environmental Sensors 1 years, 8 months ago
Most I2C devices don’t like having the power to the device cut and the reapplied, which is why the Vcc pin of the Mayfly’s I2C Grove jack is constantly powered. All the other Grove jacks switch the power on or off, but the I2C jack always has 3.3v, even with the Mayfly is asleep. So if you’re powering your Atlas board from any of the switched s…[Read more]

I think @srgdamiano should be able to help, since she has the best understanding of the libraries and commands used with the sim7080.

I’ve had 2 problems with the SIM7080G modem on the Mayfly 1.x board. I wonder if anybody else has had the same problems or has any information that would help me.
My code is uses the TinyGsm library, and some parts of the ModularSensors code but is otherwise custom code. The code has been working in the field with Mayfly 0.5 and Digi LT…[Read more]

I have tried various configurations. I have connected it to the I2C Grove slot, and I have connected it to the SDA & SCL pins. As for the power, I have gotten power through the Grove connector, and I have tried giving it power through each of the 3.3v and gnd pins. It performs the same regardless of how I have it connected.
I am using the…[Read more]

How are you connecting the sensor to the Mayfly (what pins for data and power and what jack), and are you putting the Mayfly to sleep between readings? Is the sensor being powered constantly or are you switching off the power to the sensor between readings?

I am hoping that we can use AT&T or Verizon cellular. That will make things simpler(maybe). But it’s nice to get a toolbox of useable solutions if they are needed.

Great @ldecicco – one are to note with “pio pkg install” is how it becomes part of your build process. I like to have a development build environment tree. Then a final “release” environment – and attempt to take a full snapshot of all libs used. I encapsulate the difference in text instructions and operation of the platformio.ini.

I am working on programming a Mayfly Data Logger v1.1. I am using the Simple_Logging program in Visual Studio and the PlatformIO. I am attempting to connect an Atlas Scientific DO sensor to the logger using I2C. I already have an Atlas Scientific pH sensor connected to the Mayfly, and the pH sensor is working fine. The DO sensor is not. It will…[Read more]

@rogers1313 interesting question, and I’ve been mulling over possible solutions as it seems very attractive.
The area undefined , is power, cost of the cellular gateway, and reliability of the connection.
Its possible to do the individual elements easily – 900Mhz point to point – and cellular – but then introduce a packet with the “readings i…[Read more]
