A Study on HT32F1765 MCU-Based in Smart Home Gas Monitoring

Article Preview

Abstract:

With the rapid development of today's society, air pollution is becoming one of the hottest topics of humans’ concern. Looking at the daily life, some peoples’ awareness in the dangers of indoor air pollution and household gas safety is not enough, so it may lead to a number of respiratory diseases, or "sub-health" conditions. (Such as influenza, pharyngitis and other diseases) On the other hand, some families, because of a gas leak, has not been timely warning of fires and caused the tragedy. To solve these problems, this work is designed based on low-power microcontroller as the master chip HT32F1765 100LQFP between the various smart sensors and did data exchange with the home environment monitoring system. The HT chip use as the master chip and combined with using Sharp PM2.5 gas sensors, temperature and humidity sensors, gas concentration sensor as gas sensing devices. We use all these sensors as information collection module, to collect the data information of air quality, temperature, humidity and combustible gas concentration in different rooms and different locations. The real-time data acquisition and sensor would be displayed on the touch screen. In addition, the creation of data monitoring hardware devices, as well as match the mobile phone in APP. Our users can log on the APP remotely to view home monitoring information, or to receive alarm information.. Thus, adults can safely work outside, avoiding unnecessary worry.
