Smoke alarm is a common safety device in modern houses or public places. Smoke alarm is generally composed of smoke sensor and smoke detection chip. This is also with the development of social science and technology, people's safety awareness is constantly improving, the installation of various fire safety equipment is also essential.
Smoke alarm is a kind of equipment which can give early warning in time in case of fire. It is mainly used in home, public entertainment, office, warehouse and other places. The main sensor of the ordinary smoke alarm is the smoke sensor, and as a result of the fire when the momentum is rapid, can put out the time is relatively short, usually difficult, so will generally cause serious personnel and material losses. Therefore, the smoke alarm equipped with PM2.5 sensor and smoke sensor can find the source of the fire as early as possible, send an alarm signal at the first time of the fire, and inform relevant personnel to fight and rescue, so as to minimize the loss.
Laser dust sensor module LD11 is a high-precision particle concentration sensor based on MIE scattering theory of laser, which can continuously collect and calculate particle concentration distribution, and then convert it into mass concentration, and output it in the form of universal digital interface. The sensor can be embedded with various instruments and instruments related to the concentration of suspended particulate matter in the air, such as smoke alarm or environmental improvement equipment, providing timely and accurate concentration data.
The sensitivity of PM2.5 sensor has a great impact on the performance of smoke alarm, which determines the timeliness of the smoke alarm when it encounters a situation. However, once it fails to give a timely alarm in case of fire, the smoke alarm becomes a mere device. The laser PM2.5 dust sensor developed and produced by luftmy is widely praised by the industry in terms of measurement accuracy, stability, consistency error, anti-interference and other performance indicators.
