Abstract

The invention discloses an indoor environment monitoring system, and the system comprises a fuel gas sensor, a formaldehyde sensor, an AD converter, a temperature and humidity sensor, a single-chip microcomputer, a display module, a control circuit, a fuel gas valve, and a ventilator. The fuel gas sensor and the formaldehyde sensor carry out the gas collection, and a signal is inputted into the single-chip microcomputer after being converted by the AD converter. The temperature and humidity sensor is used for detecting the indoor temperature and humidity, and inputting the signals to the single-chip microcomputer. The single-chip microcomputer respectively controls the display module and the control circuit. The control circuit is connected with the fuel gas valve and the ventilator. According to the invention, a sensing circuit is used for detecting the indoor temperature, humidity and fuel gas concentration values, compares the indoor temperature, humidity and fuel gas concentration values with parameter critical values preset by a keyboard. The ventilator is started or stopped for charging the concentration of indoor combustible gas, and the fuel gas valve is closed, and the current temperature, humidity and fuel gas concentration values are displayed in real time. Therefore, the system is higher in safety.

Description

technical field [0001] The invention relates to an indoor environment monitoring system. Background technique [0002] With the improvement of people's living standards, people have higher and higher requirements for the comfort of the indoor living environment. With the extensive use of decoration materials and the increase of daily necessities, there are many hidden dangers in the home environment. Not only in the influence of indoor temperature and humidity, but also in the concentration of harmful gases in the room. After interior decoration, the monitoring of formaldehyde concentration has attracted people's attention. According to the data of China Environmental Protection Association, the proportion of people who get sick due to the pollution-free indoor environment is gradually increasing every year, and the indoor environment has seriously affected people's health. At present, there are also monitoring instruments for indoor environment in the market, which are mai...
