Hi, I'm trying to do my master thesis and, for that, I'm needing a sensor that measures the fertility of the soil (in order to ask the worker to fertelize or not). I've found 3 sensors:
https://www.ebay.com/itm/254293224212 - Soil NPK Sensor
https://www.aliexpress.com/i/4000243250357.html - Aliexpress version of the first one
[iurl=http://[Global Version] Flora 4 In 1 Flower Plant Light Temperature Tester Garden Soil Moisture Nutrient Monitor https://banggood.app.link/FgNWVWJvGbb]https://banggood.app.link/FgNWVWJvGbb[/iurl] - Xiaomi Flora - seems to do the work for 20% of the price
My problem is that Xiaomi is not an arduino snesor but i need a way to take the iformation that it contains to use it has data for my equations wich use arduino variables.
So, I wanted to use this cheaper Xiaomi product as a nutrient sensor. Is it possible?
