The Research of Detection and Control System for Indoor Harmful Gas

Abstract:

Aiming at indoor harmful gas pollution of residents, a real-time online monitoring system is designed based on the detecting and control of harmful gases. The lower computer system make the STM32F103 microcontroller as the core and make each module been designed which included the sensor temperature and humidity acquisition, gas concentrations acquisition, sensor interface circuits, signal amplification circuit, liquid crystal display circuit, alarm circuit and so on. The upper computer make the microcomputer as the monitoring center which make on-line display of temperature, humidity and gas concentration in real-time, then people can get the indoor harmful gas data for collection and management with the upper computer. CAN bus is adopted for information transfer between the master computer and the slave computer.
