Abstract

A wireless temperature monitoring system based on low power consumption MCU MSP430 and noncontact infrared temperature sensor MLX90614 and Bluetooth transmission technology is presented. The system consists of acquisition sending module and receiving display module

acquisition sending module read temperature data from MLX90614 by means of SMBus protocol with the usage of MSP430 as core

the result is sent by Bluetooth module and displayed by receiving display module through segment LCD. The system power consumption is reduced by usage of MCU MSP430. In the area of medical equipment research and development

special requirements of pollution isolation is reached with the he

lp of non-contact infrared thermometer MLX90614

digitization networking

distribution management is realized easily by the usage of the Bluetooth transparent transmission module. Experimental results show that measurement precision can reach ± 0. 2 ℃ in the range of32

42 ℃ and the system can achieve wireless transmission

it has wide application prospect in medical device research and fabrication field.
