Regional Prevention System Design for the Photoelectric Sensor
Regional safety alarm system is a security system widely used in enterprises and institutions, residential districts and office buildings, which has a complex structure and higher costs. This design is mainly to use SCM and some simple photoelectric sensors to achieve a regional safety alarm system with high reliability and low misoperation, and its size can be easily extended according to user needs.
