Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

A WiFi-based flue gas combustion detector refers to figures 1 to 2 and comprises a shell, wherein a main control chip, a gas collecting port, a sensing unit, a wireless module and a power supply unit are arranged in the shell, and the sensing unit, the wireless module and the power supply unit are electrically connected with the main control chip; the main control chip is internally integrated with a calculating unit and a judging unit, and the calculating unit is used for calculating a comprehensive numerical value of the relevant data acquired by the sensing unit; the judging unit is used for judging whether the comprehensive numerical value is greater than a preset safety threshold value; the wireless module is a WiFi module, and the WiFi module is used for transmitting early warning information to the intelligent terminal. The smoke related data collected by the sensing unit are uploaded to a main control chip, and the calculation unit calculates the comprehensive numerical value of the related data; and if the judgment unit judges that the comprehensive numerical value is greater than a preset safety threshold value, the WiFi module sends an early warning to the intelligent terminal. Through various gas and dust detection, according to the comprehensive data, the possibility of fire alarm generation is judged before the fire, and the pre-judgment effect is achieved. If the old or children in home carelessly cause fire, and the concentration of carbon monoxide is too high to cause coma or sleep and the like without perception, other users can find out the abnormality in advance and process the abnormality.

The sensing unit comprises a dust sensor, a carbon dioxide sensor, a carbon monoxide sensor, a VOC sensor and a smoke sensor. The dust sensor is used for detecting PM2.5 and PM10, and if a fire alarm is generated; the VOC sensor is used for judging harmful gases such as coal gas and the like; the smoke sensor can judge whether a fire occurs; the carbon monoxide sensor is used for assisting fire judgment. The monitoring data of the sensors are increased along with the change of fire related substances in the air.

Furthermore, the display screen and the key module are further included, the key module is electrically connected with the main control chip and the display screen, and the display screen comprises a gas data display area, a gas concentration display area, a temperature display area and an electric quantity display area which are detected by the sensing unit. The user can operate the key module to adjust the numerical value of the sensing unit and display the numerical value through the display screen.
