About the service life
Lifespan is one of the key indicators of laser dust sensor. The laser dust sensor uses high quality and long life imported laser diode with the service life of up to 8000 hours. For the occasions that use continuously for a short time (such as detector), the default configuration 1 continuous measurement per second, for continuous use of applications (such as purifiers, air quality monitoring, etc.), you can use indirect power-on measurement to extend the service life, for example, 1 minute boot 20 seconds, 40 seconds off the service life Extend to 3 times.
