Security applications: Security systems within and outside the home, enterprise, including surveillance, burglar alarms, and access control, etc., use security PCBs to coordinate various components and signals used to detect the presence of intruders. In addition, smoke or fire alarms, electronic door locks, and motion sensors all use security PCB.
The intrusion detector in the PCB is a front-end device in the intrusion alarm system. It consists of various detectors and is the tactile part of the intrusion alarm system. Security PCB is equivalent to human eyes, nose, ears, skin, etc., and senses the temperature, humidity, changes in various physical quantities such as odor and energy, and converts them into electrical signals suitable for transmission in accordance with certain rules.
