Indoor air pollution is getting more and more attention, and indoor dust particle density is an important index to measure the degree of pollution. PM2.5 refers to the particles in the atmosphere with a diameter less than or equal to 2.5 microns, also known Particulate matter can enter the lungsRespirable Particles . PM2.5 has a small particle size, rich in a large number of toxic and harmful substances, and it stays in the atmosphere for a long time, so it has a great impact on human health and the quality of atmospheric environment.
The PM2.5 sensor's real-time detection of dust particles is the premise and important guarantee for effective prevention and control of PM2.5 pollution. PM2.5 dust particle detector can be used for: indoor and automotive air conditioning exhaust dust concentration detection; Environmental monitoring department air dust detection, pollution sources investigation; Determination of dust concentration in construction or blasting sites; Precision instruments, etc.
The PM2.5 sensor modules developed and generated by luftmy, a manufacturer of particulate matter sensors, are applied in the following fields: air purifier, air conditioner with purification function, PM2.5 detector, range hood, smoke alarm, fresh air system, dedicated PM2.5 sensor, air detector, etc.
The laser PM2.5 sensor module can be embedded with various instruments or environmental improvement equipment related to the concentration of suspended particulate matter in the air, providing timely and accurate concentration data. Application to detector, such as PM2.5 dust particles PM2.5 dust sensor real-time detection diameter less than or equal to 2.5 micron particles in the air content, and according to the content ratio of the output analog voltage signal, the signal after A/D conversion by MCU after collection, calculation, data processing, on the LED display, show the value of PM2.5.
