Braedon replied to the topic Using Modular Sensors for METER Teros 12 in the forum Environmental Sensors 10 months, 1 weeks ago
@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.

Is there a way to use the modular sensors library for METER Teros 12 sensors on the Mayfly 1.1? I’ve noticed that there is an option for the Teros 11, but not for the 12. Can the MeterTeros11.cpp file be modified to capture the electrical conductivity that the 12 measures but the 11 doesn’t? I’ve thought about just using the SDI12Sensors files to…[Read more]

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!

I am currently trying to learn and understand how to properly use the modular sensors library for the Mayfly 1.1. I have downloaded the libraries through EnviroDIY, and I am using the Arduino IDE.

Braedon replied to the topic Mayfly v1.1 technical questions forum thread in the forum Mayfly Data Logger 11 months ago
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]

Hey everyone! I’m wondering what you all have used and what alternatives exist out there for infrared radiometers or surface temperature sensors. I’ve mostly seen apogee sensors (https://www.apogeeinstruments.com/infraredradiometer/), but I’m wondering what other sensors people have used, particularly for terrestrial surface temperatures. Thanks!

Braedon replied to the topic Mayfly v1.1 technical questions forum thread in the forum Mayfly Data Logger 11 months ago
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 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.

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]

Braedon replied to the topic Mayfly v1.1 technical questions forum thread in the forum Mayfly Data Logger 11 months, 1 weeks ago
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]

Braedon replied to the topic Mayfly v1.1 technical questions forum thread in the forum Mayfly Data Logger 11 months, 1 weeks ago
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?

Braedon replied to the topic Mayfly v1.1 technical questions forum thread in the forum Mayfly Data Logger 11 months, 1 weeks ago
How do the analog pins found on the 20-pin header (pins A0, A1, A2, etc.) differ in function and purpose from the auxiliary analog pins (AA0, AA1, etc.)? From what I’ve seen, you need to connect analog sensors to the auxiliary analog pins and use an Adafruit library to get the millivolt readings because of an ADC they are connected to. I’ve…[Read more]

I am looking to connect an apogee SL-510-SS pyrgeometer to the Mayfly board. Eventually, I hope to have two apogee pyranometers on the same board as well, the SP-510-SS and the SP-610-SS.

Okay sounds good. I was also wondering, Shannon, if you might be able to help me out with something.

Braedon replied to the topic Negative Voltage Reading from Single-ended ADC Using Apogee SP-212-SS Sensor in the forum Environmental Sensors 12 months ago
Thank you for your reply! That definitely helped. I think the only thing I’m still confused on is the output channel. You mentioned that the white wire in the uppermost grove jack is connected to analog channel zero, but when I look at the board, the label next to that wire is AA1. If you could clear that up for me that would be great. Thanks for the help!
