With the aggravation of China's aging population, the difficulty of caring for the elderly has been a topic of public concern. For the elderly whose memory is declining, we have developed a portable intelligent anti-lost monitoring device for the elderly. The device uses the STM32 master microcontroller, carries the SIM868 locator, and communicates between the client and the server through the SIM card module. It uses the HTTP protocol to upload data to the cloud platform of the Internet of Things to achieve real-time positioning and geographic fence functions; It integrates voice recognition with anti-loss, sets more detailed alarm level classification, sends SMS to the guardian's cell phone, or makes a one-key call for help; uses the IMU901 module to achieve fall detection; at the same time, uses heart rate and temperature sensors to measure the heart rate and body temperature of the elderly, which is very convenient for the elderly to travel and deal with unexpected events, and greatly protects the safety of the elderly at home and on the road.
