Design of Temperature Measuring Device in Student Dormitory Based on MSP430

Aiming at the phenomenon that temperature of each dormitory is different in winter due to many factors northern colleges and universities, this paper puts forward a simple convenient measurement device. The device takes an MSP430 single chip microcomputer as control core, collects ambient data through sensor DS18B20, battery voltage with AD, displays collected OLED display screen. At same time, according measured by sensor, can output PWM speed motor simulate intelligent fan. experimental shows has high accuracy, easy use, implement.
