Hello,
Does anyone know of an arduino to measure phosphorus, nitrogen and dissolved oxygen in water? Looking for something to use as a quick measurement, not for continuous monitoring. Thanks In advance
Any Arduino can be used. Just send us links to the datasheets of the sensors needed,
JXBS-3001 does nitrogen, phosphorous and potassium for soil. Don't know if it is suitable for water though.
I should have specified. Am looking for sensors that I can use
More then one sensor might be needed...
Try Google search.
What, precisely, do you want to detect?
"Nitrogen" could stand for the gas, or any combination of millions of common compounds containing nitrogen.
All the preceding posts bring up good ideas. To summarize:
- Multiple sensors appear to be required
- "Arduino" interfacing is not always supported with pre-written libraries
- Sensors appear to be in many different categories: soil, freshwater, saltwater, and multiple subcategories
Construct your Google Search by specifying "arduino" in the criteria otherwise you are going to get too many 'hits' to research.
Thank you
Phosphorus, ph, conductivity and dissolved oxygen
There are several chemical forms of phosphorous (and phosphate-based detergents) in water, which are measured separately by analytical techniques. See https://onlinelibrary.wiley.com/doi/abs/10.1002/9781119300762.wsts0049
Electrodes that measure pH, conductivity and dissolved oxygen are available separately. They each need amplifiers to be compatible with Arduino.
