WL-AQA-A01 Things ammonia sensor is based on wireless sensor networking technology to build ZigBee, the product is used to monitor the concentration of ammonia in the air, and the signal is transmitted to the cloud or the specified device (phone, tablet, PC, etc. ), while the device can also be based on monitoring results and other control equipment linkage (exhaust system, etc.). This product is protected by CO, H2, CO2, SiH4 and other minor disturbances can be widely used in aquaculture, animal husbandry, agriculture, petroleum, chemical, environmental protection industries. Sensor wireless transmission, small size, light weight, has broad applicability, while meeting a variety of environments indoor, outdoor, etc. Product main parameters: maximum load measuring range 0-100 ppm 200ppm working life 2 years in air output 120 ± 30nA / ppm resolution of 1ppm temperature range -10 ℃ to 40 ℃ range of atmospheric pressure response time (T 90) <50 seconds humidity range 15-90% RH (non-condensing) zero output 0ppm ± 34ppm maximum zero drift (20 ℃ to 40 ℃) -8 ppm Long-term drift <5% / months recommended value of 10Ω load transmission distance of 100 meters ZigBee transmission bias voltage without
