The nuclear laboratory monitoring system was developed by integrating the stm32 microcontroller and esp32cam module.The system encompasses radiation monitoring,fingerprint recognition,and face recognition.It utilizes the G-M counter tube as a radiation detector to monitor environmental radiation in the laboratory,automatically evaluate doses,and emit alarms.Furthermore,it achieves multi-factor identity verification and ineligent attendance through fingerprint recognition and face recognition,thereby enhancing the itelligence level of the nuclear laboratory while ensuring efficiency and safety.
