sensor to measure amonnia in air

Ammonia Sensor. - Sensors - Arduino Forum

2021-05-06· 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.
