MD368 Series UART Smoke Alarm

MD368 optical smoke alarm is designed to meet the needs of applications of radio linked operating systems. Not only the alarm offers aesthetically appealing design but also comes with UART output to be integrated with RF module. The MD368 series can either serve as a smoke or smoke / heat combo alarm, or serve merely as heat alarm. MD368 has a 10-year lithium battery option.
