According to relevant experts, people in the simulation of natural environment has a certain effect on the quality of sleep, such as when it rains, or listen to the nature of water, birds, etc., can make people feel relaxed and happy, easy to fall asleep.Air purifiers can not only purify indoor air pollutants, including PM2.5, formaldehyde and so on, but also simulate the natural environment to a certain extent.

Particle PM2.5 sensor commonly used in air purifiers is particle PM2.5 sensor with laser principle. Guangzhou luftmyLD16 laser PM2.5 dust sensor USES MIE scattering theory of laser to detect dust particles in the air, which has good consistency and stability. With serial port output and PWM output, it can detect dust particles with minimum resolution diameter from 0.1 micron to 10 micron.

We spend a third of our lives sleeping, and quality sleep allows our brains and bodies to rest, helping to eliminate fatigue, stabilize emotions and restore physical strength. However, as the pace of life accelerates, insomnia is becoming a problem for more and more people. In fact, the use of air purifiers equipped with PM2.5 particle sensors can improve sleep quality to some extent.

Similarly, air purifiers often use infrared PM2.5 particle sensors,Luftmy HPD05 infrared PM2.5 sensor module uses the optical scattering principle to detect the concentration of dust in the air. The sensor is built with an infrared light-emitting diode and a highly sensitive photoelectric receiving sensor, which can directly output PWM signal or output the value of dust concentration through IIC serial port signal. The infrared sensor is suitable for air purifier, air conditioner with purification function, fresh air system and air quality testing instrument.
