Once a fire or explosion occurs, it can result in significant casualties and severe economic losses. Therefore, we need to be aware of safety precautions. According to surveys, 93% of households in the United States have at least one smoke alarm. In recent years, the number of households equipped with smoke alarms has increased, leading to almost a 50% reduction in fatalities caused by residential fires. Smoke alarms utilize smoke or temperature sensors combined with microelectronic judgment circuits to drive the alarm or electromagnetic relays, serving as a warning device for fire detection or alert purposes.

As a leading force in the field of PCB reverse engineering in Shenzhen, Dongdao Technology combines the latest EDA design software, professional PCB cloning technicians, and advanced manufacturing processes. We have the capability to clone single-layer, double-layer, and multi-layer PCB circuit boards, and are adept at tackling challenging tasks, such as the reverse engineering of smoke alarms and other complex electronic devices.
