溫度量測在家庭及工業應用上是非常重要的，本論文的主要目標是以熱電堆來設計固定平面或大區域兩種溫度量測系統，其中一種是固定平面的表面溫度量測系統(PTMS)，另外一種是大區域物體表面溫度監測系統(LRTMS)。
固定平面溫度量測系統(PTMS)係由熱電堆、微控制器、類比數位轉換器、LCD、LED、蜂鳴器、雷射指示器及編碼旋轉開關組合而成。以LCD顯示器顯示溫度值，LED點亮的顏色表示對應的溫度範圍，以RS-232或無線傳輸介面，將量測溫度值傳送到PC個人電腦，溫度數值及對應的顏色顯示於PC螢幕，蜂鳴器依據設定溫度值發聲警示。本系統為放射率可調、可攜式的多點2D平面溫度量測儀器，有效的溫度量測範圍為–20°C到115°C，視角為41° × 32° (水平×垂直)，空間解析度為4 × 4畫素，量測誤差低於±1°C。實驗結果證實本系統可監測固定平面的表面溫度變化。
大區域溫度監測系統(LRTMS)係由熱電堆、微控制器、類比數位轉換器、步進馬達及微動開關組合而成。以RS-232或無線RS-232介面傳送溫度值，以對應的顏色表示溫度範圍，顯示於PC螢幕上。本系統為大區域的表面溫度分布量測儀器，有效的溫度量測範圍為–20°C到115°C或180°C，3D掃描的空間解析度為40 × 24畫素或64 × 40畫素(水平×垂直)，量測距離低於200公分時，可獲致較佳監測效果。實驗結果證實本系統可監測室內物體的表面溫度。
上述兩種溫度量測系統可應用於分辨電器設備的高溫點、室內裝潢悶燒來源或室內人員的活動等。

Temperature measurements are very important in domestic and industrial applications. The main aim of this dissertation is to design systems with a multielement thermopile to measure the temperature of a given plane or a large-region. We design two kinds of systems. One (PTMS) is appropriate for measuring the surface temperature of a given plane, while the other (LRTMS) is suitable for determining the surface temperature of indoor objects in the large-region.
We evaluate the performance of the PTMS, which comprises a thermopile, a microcontroller (MCU), an analog-to-digital converter, a liquid crystal display (LCD), light-emitting diodes (LEDs), a buzzer, laser pointers, and a rotary encoder. We use different types of display devices such as an LCD for displaying the measured temperature and LEDs for indicating the temperature range. An RS-232 interface or a wireless interface is used for transmitting the temperature values to a personal computer (PC) for displaying them in different colors on the monitor. The buzzer/alarm in the system is activated when the threshold temperature is reached. The system is portable and can be used for two-dimensional temperature measurements; further, its emissivity can easily be varied. The effective detection range of this system is from –20°C to 115°C, the field of view is 41° × 32° (horizontal × vertical), and the spatial resolution is 4 × 4 pixels; the measurement error is confined to ±1°C. Experimental results confirm the effectiveness of the system in monitoring the surface temperature of a given plane.
We also evaluate the performance of the LRTMS, which comprises a thermopile, two MCUs, an analog-to-digital converter, two stepping motors, and four microswitches. We use an RS-232 interface or a wireless RS-232 interface to transmit temperature values and indicate the temperature range on a PC screen. The system can be used for determining the temperature distribution in the large-region. The effective detection range of this system is from –20°C to 115°C (TPAM166L3.9) or 180°C (TPLM086L5.5) and the resolution of 3D scan is 40 × 24 pixels or 64 × 40 pixels (horizontal × vertical). When the distance over which the temperature distribution is determined is lower than 200 cm, the obtained distribution is very accurate. Experimental results confirm the effectiveness of the system in monitoring the surface temperature of indoor objects.
The designed systems can be used to identify a high-temperature part in electrical heating equipment, a smoldering material hidden in upholstery, or the activities of a person in a room.
