PM2.5 real-time monitoring device

Abstract

The invention provides a PM2.5 real-time monitoring device. The device comprises a master controller and a slave controller, and the master controller and the slave controller conduct signal interaction through a wireless receiving-transmitting circuit; the master controller and the slave controller are each externally connected with a clock circuit, an alarm circuit and a display circuit, wherein each display circuit is used for displaying the data transmission state and monitoring values; the dust concentration to be detected is converted into electric quantity through a dust sensor and input into the master controller through an A / D converter, and the master controller is further externally connected with a temperature collection circuit. According to the PM2.5 real-time monitoring device, the master controller and the slave controller are combined with the wireless receiving-transmitting circuits, PM2.5 wireless monitoring is achieved, the maximum transmission distance on an open field is 1000 meters, in addition, the device further displays outgoing suggestions for outbound personnel, the current temperature and the current time while displaying the exact PM2.5 value and the corresponding air quality index, and the functions are abundant. Wireless receiving and transmitting is adopted, and therefore real-time PM2.5 monitoring for multiple points can be achieved.

Description

technical field [0001] The invention belongs to the field of electronic measurement, and in particular relates to a real-time monitoring device for PM2.5. Background technique [0002] Traditional PM2.5 monitors cannot realize the wireless monitoring function of PM2.5 or the wireless monitoring distance is relatively short, and the specific indicators monitored are not intuitive enough for non-professionals to understand, and cannot reasonably guide people to travel outdoors. Contents of the invention [0003] The object of the present invention is to provide a PM2.5 real-time monitoring device for the above defects in the prior art, which can realize PM2.5 wireless monitoring, and the detection result is intuitive and more humane. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: comprising a master controller and a slave controller, and the master controller and the slave controller perform signal interaction throu...
