In view of this, Executive Yuan legislate “Indoor Air Quality Act” in Nov. 23, 2011. Regulate the standard value of harmful gases in the indoor environment, carbon dioxide (CO2) 1000 ppm, carbon monoxide (CO) 9 ppm and formaldehyde (HCHO) 0.08 ppm. And establish regulations of management method and fines.The common indoor alarm device is fixed-point alarm buzzer, but when it was affected by environmental background sound source, such as high-decibel equipment, the buzzer won’t be able to transmit and will lead to the disaster occurred. This researchs result is a kind of LED bulb lighting device which can detect the harmful gas and provide the warning function. This study is divided into three parts. First, use TRIZ theory to evaluate the suitable device. Second, the hardware structure. The research methods are SketchuUp, Netfabb and 3Dprint for frame design and production. Third, the circuit control software. Now the physical device has finished development. And numerical adjustment by tests the harmful gas.
