Wherein, central processing unit is used to handle and coordinate the data that air mass sensor transmits, and with the data transmission that obtains to wireless communication module;
Air mass sensor is used for air quality data in the sensing chamber, and with data transmission to central processing unit;
Host computer is connected communication through serial communication modular with the wireless indoor atmosphere quality monitoring device, the wireless communication parameters of configuration central processing unit;
Wireless communication module is used for the air quality data that obtains from central processing unit is transferred to remote supervisory and control(ling) equipment.
Said central processing unit is the ATmega8 single-chip microcomputer.
Said air mass sensor adopts the TGS2602 gas sensor; This gas sensor is the peculiar smell of the airborne low concentration pollutant of perception sensitively; Like airborne low concentration cigarette pollution thing and other peculiar smell; Like ammonia, sulfuretted hydrogen etc., hydrogen, carbon monoxide etc. also there is higher susceptibility, the VOCS (VOC) of low concentration is had very high sensitivity.
Said serial communication modular adopts the MAX3232ACSE chip.
Said wireless communication module adopts the LSDRF4310M01 wireless data transmission module.
When this wireless indoor atmosphere quality monitoring device used, its principle was: host computer connects the wireless indoor atmosphere quality monitoring device through serial communication modular, thus the concrete parameter (like station number, baud rate etc.) of configuration radio communication; The simulating signal of the air quality data that central processing unit admission of air mass sensor is gathered; And be converted into digital signal through A/D conversion; Then air quality data is transferred to and remote supervisory and control(ling) equipment through wireless communication module, thereby realize remote monitoring indoor air quality.
The utility model has following beneficial effect with respect to prior art:
The atmosphere quality monitoring device wired connection mode that this wireless indoor atmosphere quality monitoring device the has overcome existing non-hand-held loaded down with trivial details defective that connects up; Can monitor the air quality of indoor environment in real time; And carry out remote monitoring through wireless network; Have simple and reliable for structurely, data transmission is stable, characteristics easy to use.
