Abstract: There are many problems in the current security system, such as poor reliability, easy damage, easy handling of false positives and time delay problem, this paper proposes a design scheme of alarm system based on GPRS security. The system uses sensors to monitor home accommodation. When a warning occurs, the sensor transmits the pulse signal to the microcontroller to achieve the goal of interrupting the program. While using light and sound to intimidate the thief, the SCM sends the alarm message to the preset number. Therefore, the owner can take further security measures to protect the safety of life and property.
