Abstract :
Based on the analysis of the infrared thermometry principle, using low power Bluetooth4.0 technology and combining software and hardware, a thermometer was designed, which can send temperature data to the mobile phone by Bluetooth4.0. After amplified the infrared temperature sensor signal of the thermometer by a instrumentation amplifier, CC2540 carries on the AD sampling, based on the infrared thermometry principle, to calculate the temperature value. Finally the temperature value will be sent to the mobile phone through the Bluetooth 4.0, and the temperature value can be plotted as a line so that we can clearly observe patient´s temperature changes for a long time. Through the actual test, the feasibility of the system was verified.
