Abstract

To provide people with a safer and more comfortable living environment, a smoke temperature and humidity system based on an AT89C52 microcontroller is designed, which can use an MQ-2 smoke sensor to collect toxic and harmful gases in the air, and then transmit the data to the microcontroller through AD conversion, and also design a temperature and humidity monitoring module, which can be sent to the microcontroller through the DHT11 sensor sampling into digital quantities. Finally, the smoke concentration collected by the two sensors as well as the temperature and humidity values are displayed through the LCD, and an alarm feedback information module is also designed. The design is simple to operate and has good stability.
