Ammonia Sensor. Sensors Arduino Forum

· The ammonia gas sensor you looked at will meaure ammonia in air, and it is less sensitive than your nose is. Yes, That is my ideas, I want to determind the total concentration of ammonia in aquarium water. It consists of NH3 and NH4+. As I know, to determind the concentration of NH3, we have to measure the pH and total concentration of ammonia.

Ammonia gas sensors: A comprehensive review ScienceDirect

· The major advantages of FET NH 3 gas sensor are low power consumption in ambient conditions and costefficient production; however, the relatively high operation temperature (100∼300 o C) is normally required for an accurate measurement since the preadsorbed species, such as water or hydrocarbons, disturb the sensing process severely at room temperature .
