The hardware architecture of the device consists of temperature and pressure sensors, signal conditioning circuits (SCC), single chip microcontroller, LCD display and GSM modem. A built-in software algorithm acquires temperature and pressure, processes, transmits, displays and stores in the built-in microcontroller EPROM. A preset trigger level for the temperature and / or BP is stored in the EEPROM of the microcontroller. Once the desired programmed trip level of either signal is reached, the microcontroller downloads the current value of the temperature and BP to the GSM modem. Then the GSM automatically dials the pre-selected mobile phone number and transmits both parameters as a normal mobile message to a doctor, nurse and / or emergency personnel. A short database containing these parameters is collected and stored in a lookup table. This database can be used to track patient temperature and BP history if necessary.
