MQ137 NH3 Gas Sensor

Detects ammonia, which builds up in poultry houses, livestock barns and around industrial refrigeration systems where it is used as a refrigerant. In agriculture, ammonia concentration directly affects animal health and productivity, making continuous monitoring genuinely valuable rather than merely a safety measure. Provides analogue and adjustable digital outputs and needs the usual MQ warm-up. Detects ammonia in agricultural and industrial settings; Directly relevant to livestock health monitoring; Analogue output plus adjustable digital threshold; Stable long-term response
