Abstract
In order to achieve monitoring the concentration of gas indoor digitally and intelligently and alarm timely, a high-performance instrument is developed with sound and light features tips and infrared remote control by the article ,which can achieve monitoring the concentration of gas and alarm in the various occasions.
ATmega16L AVR microcontroller is the core hardware to the system, software is used to achieve auto-components zero and non-linear compensation, through real-time collection, data processing can accurately monitor the content of gas indoor, which will be send to PC monitor platform to be processed by the long-distance data transmission module, and design the infrared remote control transmitter and receiver, the system's various parameters of non-contact settings, LED digital display of the auxiliary module, dynamic display of gas concentration, when measured over the concentration of gas in the gas Numerical scheduled, will have a alarm with sound and light.
The system is simple in structure, small size, use and easy installation, maintenance or maintenance-free low-cost, high accuracy, non-contact infrared remote control, real-time control and data-handling capacity of the characteristics can be applied to other test systems.
