Ammonia probe - Sensors - Arduino Forum

May 06, 2021· They do tend to be quite expensive though, an ISE for ammonia looks to be $500 to $1000. And some of those membranes don't last long and almost none can stand up to constant monitoring. There are ammonia gas sensors that are supposed to be pretty accurate and if the OP knows his basic chemistry he may be able to exploit one of those.
