摘要： A gas concentration measuring device and a gas concentration measuring method are provided. The gas concentration measuring device includes an IR gas measuring module, a circuit processing module, and a display module. In the gas concentration measuring method, the IR gas measuring module measures concentration of a gas and outputs a concentration signal corresponding to the measured gas concentration. The circuit processing module receives the concentration signal and processes the concentration signal to obtain an electrical signal in linear proportion to the gas concentration. The display module receives the electrical signal and displays the gas concentration corresponding to the electrical signal.

摘要： An air-quality conditioning device is proposed, which can be singly used or used in combination with a small air conditioner. In an enclosed space, concentration of carbon dioxide is detected by a carbon dioxide concentration detecting module of the device. While the detected concentration of carbon dioxide reaches a predetermined upper limit value, an air conditioning mechanism is driven by an air-conditioning controlling module for introducing external fresh air to the space. While the carbon dioxide concentration reduces to a predetermined lower limit value, the air conditioning mechanism is driven for stopping the introduction of the external air. Therefore, the carbon dioxide concentration can be properly adjusted in the space so as to maintain good air quality therein.

摘要： A digitally-controlled pyroelectric signal sampling circuit is proposed, which is designed to process the alternating current (AC) signal from a pyroelectric device, such as a pyroelectric infrared sensor, such that the AC signal is converted into direct current (DC) signal. The proposed digitally-controlled pyroelectric signal sampling circuit is characterized by the use of a microprocessor in conjunction with a crystal oscillator whose operating characteristics would be substantially unaffected by temperature changes in the ambient environment. This feature allows the generated trigger signal and sampling signals to be substantially fixed in frequencies and timings, without drifting due to temperature changes in the ambient environment, and therefore allows the digitally-controlled pyroelectric signal sampling circuit of the invention to provide a more accurate DC output than prior art. Moreover, the utilization of a microprocessor in place of analog-type delay circuitry can help simplify the hardware architecture and thus save manufacturing cost.
摘要翻译：提出了一种数字控制的热电信号采样电路，其被设计用于处理来自热电装置（例如热释电红外传感器）的交流（AC）信号，使得AC信号被转换为直流（DC）信号。所提出的数字控制热电信号采样电路的特征在于使用与晶体振荡器结合的微处理器，其工作特性将基本上不受周围环境温度变化的影响。该特征允许生成的触发信号和采样信号基本上固定在频率和定时中，而不会由于周围环境中的温度变化而漂移，因此允许本发明的数字控制热电信号采样电路提供更精确的DC 输出比现有技术。此外，利用微处理器代替模拟延迟电路可有助于简化硬件体系结构，从而节省制造成本。
