Diseño e implementación de un sistema de adquisición de señales biométricas mediante mensajes SMS

Abstract

Acquisition system of biometric signal “body temperature of a person” –using mobile technology (cell phone) was designed – to provide the ability to transmit wirelessly to the cell phone of the treating physician. Research techniques, logical and systemic methods were used to model the prototype, programming software as Arduino1.5.6 and C Basic language, LM35 Sensor which is responsible for monitoring body temperature, Arduino diecimila module, electronic devices, LCD display messages, GSM SIM900 transmission and reception module for the wireless communication. This device was designed with the Arduino diecimila module as the main brain, responsible for collecting the data transmitted by the sensor 1m35 converting analog data to digital using programing techniques on Arduino, that exceed the established range as normal body temperature-the SIM900 module scheduled to AT commands (which are coded instructions that provide communication modems)-will send a text message to the cell phone of the treating physician with the temperature data. Test runs were performed using the device and an electronic meter body temperature which gave a range of accuracy of +/- 2 degrees C, and when the transmission range of 1 minute in the sending and receiving of message, obtaining and effectiveness of 95% in the performance of tests, may be used anywhere in the field of medicine, coming to meet the proposed objective.
