Sensors are interfaced to the embedded world which constantly records data and the data is fetched through server and analysed through graphical representation. The attached sensors on patient’s body form a wireless body sensor network which measures heart rate, ECG and body temperature. The project can detect the abnormal conditions, issue an alarm to the patient and present a graphical view to the physician.
Main Components used in the project
- LM35 Temperature sensor
- AD8232 ECG Module
- Digital Heartrate sensor - BPM
- STM32M0 MCU
Internally , 12 Bit ADC is used for conversion of values from analog to digital. Therefore , while calcuating temperature , the formula that is implemented is = 3.3 * 1000 /4095 (Where 3.3 V is the Internal Compartor voltage to ADC)
