1、 Product Introduction of Low Cost Outdoor Air Environment Detector

The BYS750-ZX low-cost outdoor environment detector is a device developed and produced by Shenzhen Boyunchuang Environmental Technology Co., Ltd. for measuring indoor air quality. It is mainly used to measure outdoor temperature and humidity PM2.5、PM10、 Real time detection and provision of effective data for noise and other concentrations, using outdoor waterproof materials to ensure stable outdoor operation. This device is mainly suitable for environments such as digital urban management, smart cities, construction sites, garbage dumps, demolition sites, docks, industrial parks, and community office windows.

2、 Parameter Introduction

PM 2.5: Refers to particulate matter in the atmosphere with a diameter of less than or equal to 2.5 micrometers, also known as pulmonary particulate matter. Its diameter is less than 1/20 of the thickness of a human hair. Although PM2.5 is only a small component of the Earth's atmospheric composition, it has significant impacts on air quality and visibility. In February 2013, the National Science and Technology Terminology Review Committee named PM2.5 as fine particulate matter in Chinese. The chemical composition of fine particulate matter mainly includes organic carbon (OC), elemental carbon (EC), nitrate, sulfate, ammonium salt, sodium salt (Na+), etc.

PM 10: Inhalable particulate matter, usually referring to particles with a diameter of less than 10 microns, also known as PM10. Inhalable particulate matter persists in ambient air for a long time and has a significant impact on human health and atmospheric visibility

Noise: It is a type of sound that causes irritability or excessive volume, posing a threat to human health. Noise pollution mainly comes from transportation, vehicle honking, industrial noise, construction, social noise such as music halls, loudspeakers, morning markets, and loud human speech. Research has shown that when the noise level is 90 decibels, the sensitivity of rod cells in the retina to distinguish light brightness begins to decrease, and the response time to recognize weak light is prolonged; When reaching 95 decibels, the pupils will dilate; When reaching 115 decibels, the adaptability of the eyes to light brightness will decrease by 207. In addition, people who are exposed to noise for a long time are most likely to experience eye fatigue, eye pain, blurred vision, and tears.
