GSM SMS for elderly physiological intelligent monitoring based on 51 MCU This design consists of STC89C52 MCU circuit + flame sensor circuit + acceleration sensor + heart rate sensor circuit + sim800a_ GSM module circuit + power supply circuit. The system monitors whether the elderly fall down, whether there is fire around and heart rate in real time. 1. If the flame sensor detects a flame, the GSM sends: fire! 2. If adxl345 detects that an old man has fallen, the GSM sends a specific mobile phone: fall! 3. If the heart rate sensor detects that the heart rate of the elderly is higher than 120, the GSM sends a message to a specific mobile phone: high heart! 4. Pay attention to the design of a power on, each of the above conditions can only trigger a report SMS, will not be sent continuously, to prevent repeated sending, please rest assured to use. 5. SMS processing process is indicated by GSM signal light.
