Indoor air quality monitoring and adjusting system based on Internet of Things

Abstract

The invention discloses an indoor air quality monitoring and adjusting system based on the Internet of Things. The indoor air quality monitoring and adjusting system comprises an indoor PM2.5 detector, an outdoor air detector, a central controller, a wireless communication module and air purification equipment. The central controller is connected with the air purification equipment. The indoor PM2.5 detector detects the indoor PM2.5 parameter, and the indoor PM2.5 parameter is transmitted to the central controller through an indoor wireless data transmission system. The outdoor PM2.5 detector detects the outdoor PM2.5 parameter, and the outdoor PM2.5 parameter is transmitted to the central controller through the wireless data transmission system. The central controller is used comparing the indoor PM2.5 parameter and the outdoor PM2.5 parameter with standard PM2.5 parameters, comparison results are operated automatically, and an adjusting command of the indoor PM2.5 parameter is generated. The air purification equipment is turned on or turned off by the central controller according to the adjusting command.

Description

technical field [0001] The invention relates to the field of air detection, in particular to an indoor air quality monitoring and regulation system based on the Internet of Things. Background technique [0002] Living environment and working environment are the foundation and guarantee of people's life and work. With the continuous increase of urban population, the pace of urbanization is accelerating, people's urban work and life rhythm also increases, and indoor air quality is also gradually declining. People begin to pay more and more attention to the environment in which they live and work, and the awareness of safety precautions is gradually improved, which not only requires the humanization and comfort of the indoor environment, but also puts forward higher requirements for intelligence and security. [0003] In recent years, due to the deterioration of air quality due to environmental pollution, a large number of indoor air quality detection devices have appeared on t...

Problems solved by technology

[0003] In recent years, due to the deterioration of air quality due to environmental pollution, a large number of indoor air quality detection devices have appeared on the market, mostly to detect the content of PM2.5 in the air, plus organic compounds (VOC), formaldehyde and air quality index (AQI) ,The existing air quality detection device is limited by the structure, resulting in inaccurate measurement results, and the existing air quality detection device cannot be combined with the air purification device to automatically purify the indoor air
