Smoke, gas alarm as an important product in the field of security alarm, through smoke, gas alarm to the surrounding environment to identify, determine whether there is a fire, toxic gas leakage and other risks, and produce early warning alarm. Therefore, low false positive rate, high stability sensitivity, reliability is an important measure of products. The development of this kind of product depends on the development of optical, gas, temperature sensor, in addition to sensor factors, smoke, gas alarm technology mainly manifested in the design of the product circuit and software technology, data signal technology and manufacturing process, scientific design can greatly improve the general degree of equipment, the power consumption, function, The degree of integration and false positive rates have an important impact.
Due to the continuous expansion of the application field of smoke and gas alarm, different levels of requirements are required for its accuracy, performance, stability and false positive rate in different environments. Therefore, the use of advanced technology and technology, the selection of appropriate optical maze, gas sensors, to promote the smoke, gas alarm industry to low power consumption, low false alarm rate, alarm signal wireless long-distance transmission, multi-functional, integrated and systematic development will be the industry's development trend.
With the development of wireless Internet of Things communication technology and the increasing demand of smart home and smart city, the technology upgrade of smoke alarm will accelerate the upgrading of traditional products, bringing explosive growth to the new demand in the intelligent era of the security industry.
