Embodiment Construction
[0009] Such as figure 1 As shown, the wireless air quality detector of the present invention is composed of four parts: a sensor combination unit, a data processing unit, a wireless communication unit, and a power supply unit. Among them, the sensor combination unit consists of air dust particle sensor, temperature and humidity sensor, formaldehyde VOC sensor, harmful gas sensor, CO 2 Combination of one or two or more arbitrary sensors among sensors, CO sensors, and total bacterial colony sensors. The output signal of each sensor is processed by the data processing unit for filtering, amplification, analog-to-digital conversion, calculation, etc., and then the data is transmitted to mobile terminal devices with wireless Internet access functions such as mobile phones and tablet computers through the wireless communication unit. The application software installed in the system performs detection and control, reading, storage, analysis and communication with remote servers on ...

Abstract
The invention discloses a multifunctional wireless air quality detector, and a detection result public sharing method. Environmental air quality is detected via one sensor or an arbitrary combination of more than two sensors selected from an air dust particle sensor and a temperature and humidity sensor, a methanol VOC sensor, a harmful gas sensor, a CO2 sensor, a CO sensor, and a total bacterial count sensor. According to the detection result public sharing method, signals output by the sensors are subjected to treatment, such as smoothing, amplification, analog-digital conversion, and calculation, using a data processing unit; data is transmitted to mobile terminal devices, such as mobile phones and tablet personal computers, with wireless network connecting functions via a wireless communication unit; and detection control, reading, storing, analyzing, and communication interconnection with internet remote servers are realized via application softwares in the mobile terminal devices, so that location-based air quality data sharing and public sharing among users are realized. A power supply unit is used for providing the sensors, the data processing unit, and the wireless communication unit with power; and arbitrary one or a plurality of modes, including NFC, Bluetooth, and point-to-point directly connected Wifi, are adopted by the wireless communication unit.
Description
technical field [0001] The invention relates to the technical field of environmental detection, in particular to the technical field of air quality detection. Background technique [0002] Existing air quality testing equipment is bulky and expensive. It is mostly used as a testing tool for professional testing personnel or for fixed-point testing in fixed areas, and its functions are relatively single, which cannot meet the needs of ordinary people who want to know the air quality of their environment anytime, anywhere. Contents of the invention [0003] The problem to be solved by the present invention is: to develop a portable device that can be put into the pocket of clothes, equipped with air particle detection, formaldehyde VOC gas concentration detection, temperature and humidity detection, CO 2 It is a high-quality and cheap multi-functional wireless air quality detection instrument with multiple detection functions such as detection, CO detection, and total number...
