1、 Introduction to indoor VOC gas transmitter

BYC100-VOC indoor VOC gas transmitter is a device developed and produced by Shenzhen Boyunchuang Environmental Technology Co., Ltd. for indoor air quality. It is mainly used to measure the content of VOC gases in indoor air, provide effective VOC concentration data, remind users to take safety measures, and drive functions such as fresh air system linkage, providing users with a comfortable home environment. The product adopts original imported metal oxide sensors and computing chips, which have the characteristics of high precision, high resolution, and good stability. Widely used in building HVAC, building energy conservation, smart homes, underground garages, airport stations and other places.

2、 Gas Introduction

VOC stands for volatile organic compounds. In the ordinary sense, VOC refers to volatile organic compounds; However, in terms of environmental protection, it refers to a type of volatile organic compound that is reactive and harmful. The objects that people come into contact with in their living environment emit this substance at all times. Working and living in buildings containing VOC substances, some people may experience headaches or blurred vision, known as' new house syndrome '. This has an impact on human health. Not only has the VOC issue of home decoration materials received attention, but in recent years people have also begun to pay attention to the VOC issue of electronic devices.
