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.
