We want to make a small run (~10 boards) of a PCB board we’re using in a dissolved oxygen autochamber. I am new to the world of PCB manufacturing and working with Eagle so I’m barely familiar with the terminology, file requirements (e.g., Gerber files), etc. Thus please excuse my ignorance. I currently have a BRD and SCH file in Eagle (my…[Read more]

We ended up taking the median value of 10 measurements taken 1x/second every 5 mins. However, what eventually worked (if I’m remembering this correctly; this was my dissertation research done in 2016-2019) was clamping an RF ferrite…[Read more]

Thanks for your help…we’ve now been able to successfully register the FONA and ping the internet. We’re still not able to post to the internet though. I’m going to going to make anohter separate post for this question in the hope that others will also see it since it’s a new question.

This past May I finally deployed 4 of 6 sensor nodes as part of an Arduino-based wireless sensor network collecting hydrogeochemical data at my research site in the remote coal fields of eastern KY. Historically (like 12-18 months ago?), we’ve been able get a connection up on the ridge at the site with the Adafruit 2G FONA (SIM808) paired…[Read more]

I’d suggest looking at the Atlas Scientific sensors…they have one for measuring electrical conductivity across a range of salinities: https://www.atlas-scientific.com/conductivity.html. We’ve been using them with fairly good success for the last several years. They do foul rather quickly if there is iron in your system, and we’ve…[Read more]

We are developing a data logger to collect climate, water chemistry (Atlas Scientific sensors) and water level data (Decagon CTD-10). We are using the Arduino Mega as the primary data logger with a separate “proof-of-life” (POL) system (read below in next paragraph) on a separate board using an Arduino Pro Mini programmed as an Uno.

Stephanie Fulton again. I was wondering how often you read the Decagon CTD-10’s using the SDI-12 library when you’re datalogging? We’ve been running them here in the lab to test the accuracy using Arduinos (Megas and Unos primarily) and the SDI-12 library.

Perhaps I was mixing it up with the Sodaq Mbili. That’s good to know.

I’ve got several CTD-10’s that I”m including in a wireless sensor network and would like to use them with an Arduino Mega, but we haven’t worked with SDI12 yet. Thus the code would be greatly appreciated.
