Air pollution results in millions of premature deaths throughout the world each year. Rapid industrialization has wrought intense levels of air pollution that pose a serious threat to people’s health. Air purifiers are widely used as home appliances, effectively removing PM2.5 and improving indoor air quality. How to choose an air purifier and how to exactly know its purification effect? Its built-in dust sensor is the key and it can realize intelligent monitoring and automatic control.
If the requirement for measurement accuracy is not so strict and you only need to know the dust concentration tendency, Pulse Sensor’s laser dust sensor PS5308-M/B is a good choice. Featured with rapid response time, this laser dust sensor has stable performance and is cost-effective. If you also need to output the measurement value, our laser dust sensor PS5308-M/B is highly recommended.
As we know, the change of dust concentration is not as easily perceivable as that of temperature and humidity. So more consumers want to know the accurate real-time dust concentration value on the screen of the air purifier. Pulse Sensor’s laser dust sensor PS5308A series become the best option. It adopts laser scattering technology and can accurately measure PM2.5 in real-time. Quick response times (a few seconds) are available for fitting changes in indoor dust concentration. And the measurement accuracy will not be influenced by the indoor temperature.
In addition, in recent years, air purifier has added new functions for fighting against the formaldehyde odor in new homes. So a formaldehyde sensor is necessary. Our formaldehyde sensor PS5310 adopts a nanomaterial membrane and can accurately measure the indoor HCHO concentration, effectively resisting the interference of VOC such as alcohol.
Air purifiers need to be equipped with different types of gas sensors to meet various demands from customers. Hence, air quality sensors are important in the air purifier industry. Pulse Sensor has developed and manufactured many kinds of indoor air quality sensors, such as infrared dust sensor PS53013, carbon dioxide sensor CS200 and multifunction air quality module MM201 which can detect PM2.5, VOC, temperature and humidity.
