Guidance Needed: Integrating pH and TDS Sensors into Underwater Drone

General Discussion

Hi Blue Robotics Community,

I’m currently working on an underwater drone as part of my final year project. One of the key features I want to incorporate is water quality testing, specifically using pH and TDS sensors.
But Im new to rpi and

Hi @Mubeen -
Welcome to the forums! It seems like your post was cut-off mid sentence. Did you have a question about how to use those sensors? This guide on Node-RED may be helpful, as well as this one that details connecting devices.

Sorry, I just saw how my post ended up.
I was trying to ask how do I integrate these sensors with the ArduSub or the blueos so I can see the ph and tds sensor data on the surface computer.

I was thinking to use an aditional arduino nano but dont have any idea how to link that arduino to the main Rpi any help is much appreciated.

Hi @Mubeen -
Depending on the output of those sensors you may be able to directly connect them to the Pi, but an Arduino is also a good solution. Both links provided previously should be helpful in achieving your goals!
