빌딩 제어용 무선 센서 네트워크를 위한 온도 센서의 설계 및 성능 분석

In this paper, we develop sensor node to measure temperature for wireless sensor network in building controls. Sensor nodes on characteristic have to be small to reduce the cost. Circuits for MCU, wireless communication and temperature sensor have been integrated in small PCB(Printed Circuit Board). As a result, It may cause heating of PCB. We compare performance of built-in temperature of MCU MSP430(TI) and temperature sensor SHT11(Sensirion). And, When SHT11 measures temperature, we conduct experiments if heating of PCB have a effect on data measured. In experiment, we use mercury thermometer calibrated and thermistor temperature probe using multimeter to set exact reference temperature.
