Based on MSP430 single chip microcomputer

a portable infrared thermometer used for electric power equipments is designed. The thermometer locates measurement location using radio frequency identification（ RFID） technology. And based on noncontact and distant measurement characteristics

the design uses infrared temperature measuring sensor MLX90614 to measure the target temperature; using environment temperature sensor to collect environment temperature

the equipment corrects the target temperature according to the principle of infrared temperature measurement. The system built-in SD2200 time module to record measuring time accurately. Built-in USB read-write module to record the location

target temperature

environment temperature

modification temperature and measuring time in the internal SD card for importing computers conveniently and generating report. The portable thermometer puts an end to the missing and wrong record during power checking

and generates reports to make reading convenient

and greatly improves work efficiency.
