Description

technical field [0001] The invention relates to a smart home air quality monitor with wireless communication function. Background technique [0002] With the improvement of the civilized level of social life, people's pursuit of a better life requires a higher quality of life, and the quality of family air quality directly affects people's physical and mental health, and even is related to personal safety. Use gas detection technology to measure the concentration of toxic, harmful, flammable, oxygen and other gases in the air, collect relevant concentration values ​​through single-chip microcomputer, analyze and obtain the current air quality situation, and can display it to the user in real time, and also provide over-limit alarm, low The air quality monitor with limited alarm was born. [0003] A wireless network is a technology that can connect terminals such as personal computers and handheld devices (such as PDAs and mobile phones) to each other in a wireless manner. ...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned handheld product solution has only one gas sensor, which cannot correctly evaluate the current air quality situation, and has a single function

Due to the use of batteries for power supply, when configuring gas sensors with high power consumption, it cannot provide reliable working hours that are satisfactory to users

[0006] The above-mentioned box-type detection instrument is bulky, and it is very inconvenient for home use

And the cost is expensive, it is difficult for families to popularize

[0007] The above two types of products do not have wireless communication functions, can only be displayed on the spot, and cannot be integrated into the smart home system

[0008] The above two types of products only realize the measurement and display of the gas content in the air, and cannot be linked with the air purifier to realize active air purification
