Design of Multi-functional Physiological Signal Acquisition and Wireless Transmission System
The design is based on the ultra-low power microcontroller MSP430. It is designed and developed to measure the temperature and heart rate pulse and blood flow velocity by using temperature sensor, ultrasonic module, heart rate pulse detection sensor, global satellite positioning module, global mobile communication system and wireless transmission module. Anti-lost wireless transmission system. The terminal through the positioning system, the temperature sensor pulse detection sensor and the ultrasonic module to obtain the location information and physical health of the elderly, and then in the form of short messages sent to the GSM through the SMS to receive the phone terminal, to achieve the location of the elderly and their physical condition more comprehensive Real-time monitoring, but also through the Bluetooth data upload to the database, to achieve the data storage and analysis.
