Abstract
The traditional human comfort meter has the following defects: the interface is not uniform; the operation is cumbersome and complicated; the interface is unfriendly, and the stability and adaptability are poor. This paper presents a design scheme for human comfort instrument based on embedded system, using S3C2440 embedded development board and the sensors to collect the real-time temperature, relative humidity and wind speed data and to process the collecting data; then obtaining the human body comfort value according to the basic algorithm of human body comfort instrument; giving the human comfort conclusion according to the diastolic index range of human comfort, and showing the temperature and humidity, wind speed, comfort value and conclusion through writing the Qt graphical user interface program. At the same time, the human comfort instrument has the data storage function. The human comfort instrument is high in integration, strong in real time, high in sensitivity, stable and reliable, and it meets the development goals of the intelligent meteorological service, and meets the demand of the meteorological service that is closer to life, and it has broad development prospect.
Highlights
Human comfort is a comprehensive reflection of the human body’s meteorological elements such as temperature, relative humidity and wind speed, and is a requirement for higher quality meteorological services

Summary
Human comfort is a comprehensive reflection of the human body’s meteorological elements such as temperature, relative humidity and wind speed, and is a requirement for higher quality meteorological services. Guangdong Province has begun pilot deployment, and plans to cover 80 to 90 bio-comfort measuring instruments covering the whole province This “bio-comfort measuring instrument”, which reflects the human comfort index, is the first in the country of the scientific research team of the Guangdong Provincial Meteorological Bureau. It has been piloted in Guangzhou and Shenzhen in 2013. Preliminary design of a human comfort meter based on real-time operating system, using embedded development board and sensor to collect the temperature, relative humidity and wind speed data of the location in real time, and process the acquired data, and obtain the human body according to the basic algorithm model of human comfort. The human comfort meter has data storage function and can expand the alarm function
