@srgdamiano could I get your help with these h/cpp files I created for the Teros 12 sensors? I am having some issues with my sensors not getting values other than -9999 when I have multiple Teros 12 sensors connected. When I use the Teros 11 modules, they all record together, which leads me to believe I set up my h/cpp files wrong. Could I get…[Read more]

Yes, these two modules can be set up like a wire. I got a Mayfly to send information over the Pro S3B module to another module connected to a computer. I set them up on the XCTU in transparent mode, set the network IDs to be the same, and told the sender XBee what the serial address is of the receiver XBee. In transparent mode, anytime data is…[Read more]

Okay, so what do you think would be the best way to pull out the data generated from the logger object’s logData()? If it is easy to access it, then I feel it shouldn’t be too hard to just jump to a Serial1.print() statement once the logData() method is complete to send the data. Am I thinking this through correctly?

@srgdamiano would you know if the XBee Pro S3B modules can be used with the ModularSensors library? I know how to send data over them using Serial1.print(), but I would like to use these 900 MHz modules with ModularSensors if that is possible. Thanks!

Can a 900 MHz XBee radio be used with the ModularSensors library? I noticed that there is are DigiXBee.cpp and DigiXBee.h files in the modems folder. Can modem objects created with that class be used with the logAndPublishData() function found in most ModularSensor examples that use XBees, or is there a different way of integrating 900 MHz XBee…[Read more]

@srgdamiano I made a header and cpp file for the Teros 12 by copying the 11 files and adjusting them. When I try to use it, the outputs recorded to my SD card are all -9999 values, and the column headers for the variables are never added (but it will add the headers for the other variables besides the Teros). I get the same problem when I use the…[Read more]

Okay, sorry I am not very software savvy (especially when it comes to C++). Would you suggest just copying and pasting the Teros 11 sensor files and then just adjusting the copy to handle the Teros 12? I’m not very confident in my abilities to make a new module that captures everything correctly.

@srgdamiano would you know how to best approach this?

I was! For some reason my Adafruit folder didn’t include the ADS1015.cpp and ADS1015.h files. I have my library up to date now though and it’s working great. Thanks!

Okay, gotcha. It’s of interest for me because I am looking at attaching multiple apogee pyranometers and pyrgeometers to the Mayfly that are all analog outputs. Because the pyrgeometers also require adjustments based on an internal thermistor reading, it would require more than 4 analog pins, so I am just seeing if I could get a decent resolution…[Read more]

Is the 3.3 V for the 10-bit ADC on the Mayfly a value that is fixed, or can it be changed? I don’t know if this is related or not, but does the ADC voltage come from the default analog reference, or is it completely different? Could the analog reference voltage be lowered, using the analogReference() function, giving us a higher resolution as a…[Read more]

I’m wondering when the LTE Bee modules and RS-485 adapters will be in stock. Thanks!

I am very new to the world of electronics and circuit boards. I am a graduate student of civil engineering looking to deploy snow sensing stations using the Mayfly. They will be satellite stations around an existing piece of infrastructure that already has radio communication set up with Campbell Scientific data loggers. I don’t think the network…[Read more]

Okay, so this is what I have now for my sender code:

#include <Wire.h>
#include "Sodaq_DS3231.h"

void setup() 
{
  pinMode(18, OUTPUT);
  digitalWrite(18, HIGH);
  Serial1.begin(9600);
  Wire.begin();
  rtc.begin();
  delay(3000);
}

void loop() 
{
  digitalWrite(8, HIGH);
  rtc.convertTemperature();
  
  Serial1.print(rtc.getTemperature());…

Hello, I am new to using Mayflies and XBee modules, so I’m hoping I can get some help here since the modules I’m planning on using are the 900 MHz XBee Pro S3B. Programming the modules correctly in the XTCU is something I don’t entirely grasp, but for the moment I will focus on programming the Mayfly.

Right now I am just trying to get two…[Read more]

I am confused on how we get the 0.1875 conversion factor for the 16-bit ADC. Does it operate on a different voltage? In my mind, if the board operates at 3.3 volts and there are 65,535 bits, then you would be multiplying the analog reading by 3300 mV / 65,535 bits, which is 0.050 mV / bit.

I’m asking because I am looking at connecting two apogee…[Read more]

Okay, thank you Shannon! I have a follow-up question. So when using the AuxAnalog pins, from my understanding you have to multiply the digital signal by 0.1875 to convert it to a millivolt reading. Would you need to do the same if you were to use the other analog pins (A0, A1, ,etc.), or is the 0.1875 value unique to the ADS1115 ADC?
