Brief introduction: This paper designs an Internet of things laboratory security early warning system based on STM32 microcontroller and ZigBee network. The system includes monitoring node, STM32 microcontroller, GSM communication module and administrator mobile phone. When the monitoring node detects the abnormal data, it sends the abnormal information to the STM32 main control module through ZigBee network. The STM32 main control module calls the administrator's mobile phone to remind them by controlling the GSM communication module. The administrator arrives at the scene for processing at the first time. The system can play a good role in campus laboratory security early warning.
