Ammonia sensor for fish tank monitoring project


Hi everyone, need some help regarding my project. I want to make a fish tank monitoring system that can read 3 data which are pH, turbidity and also ammonia level inside of the fish tank. May I know does there any ammonia sensor that can be submerged into the water? I really hope I’ll get the answer as soon as possible. If so where can I get it and how much does it cost.

FYI, I’ll use Arduino ATMega 2560 as my microcontroller. I hope that ammonia sensor is compatible with Arduino boards…



We don’t have an ammonia sensor on but as far as I know, they’re quite expensive.
Good luck with your project.
