Aiming at issues exist in gas leak detection and alarm device leak such as detection precision is low
alarm mode is single
design a portable CO gas leak alarm device. The alarm uses MSP430F135 chip as control core
use sound and light
vibration
SMS module as alarm body
CO volume fraction is obtained by CO sensor
through data de-noising
amplification
A / D conversion
security authentication
real-time display
alarm trigger and other processess to complete real-time monitoring and processing of gas leak. In order to both satisfy two ways of installation and portability
built an external power supply and charging module automatically switches
