Sell Module Ammonia NH3 Gas ☄Shiwaki♪MQ137 Detection Sensor Qualitative best price

Description: Mainly used for qualitative detection for home industrial environments portable gas detection equipment suitable for containing ammonia gas detection sensor gas sensors tested concentration range: 5 to 500ppm Main components: ammonia gas sensor. Module with level signal output with alarm signal indicators. The sensor module with analog signal output voltage range: 0-5V Active low level signal outputs can be driven PNP transistors can also be connected microcontroller IO port. The analog output voltage increases with the concentration the higher the concentration the higher the voltage. High sensitivity to ammonia trimethylamine ethanolamine gas. With a long service life and reliable stability. After preheating with fast response and recovery characteristics. With mounting holes to facilitate fixed installation. The probe can plug design easy to test. Module with temperature compensation function adaptability and more reliable. Specification: Heating voltage: DC5±0.2V Working current: 180mA Circuit voltage: DC5V (Max DC 24V) Load resistance: 10K (adjustable) Test concentration range :5-500ppm Clean air voltage: < 1.5V Sensitivity:> 3% Response time: < 1S (30-50 minute warm-up the theory preheating time 48 hours) Recovery time: < 30S Component power consumption: ≤ 0.9W Working temperature: -10 ~ 50 oC (nominal temperature 20 oC) Humidity: 95% RH (nominal humidity 65% RH) Size: 35mm × 40mm × 28mm Package Includes: 1 Piece Ammonia Sensor Module ☄Shiwaki♪MQ137 NH3 Ammonia Gas Sensor Module Qualitative Detection 140626078-2480256134
