Im trying to make an automated fish tank and my biggest problem is that i cannot find the right sensors to measure the nitrite, nitrate, ammonia, and PH of the water. i have found a few ph sensors i can use but i still need the guidance for making it work with the arduino. any help would be greatly appreciated.

It depends on the sensor and how it "reports" the reading. links would help us help you!
