Do you need to be able to sense CO2 concentrations of up to 100%? If so, the STC31 is the sensor for you! The Sensirion STC31 thermal conductivity sensor has two CO2 measurement ranges: 0 to 25 vol%; and 0 to 100 vol%. The measurement repeatability is 0.2 vol%, with a stability of 0.025 vol% / °C. The measurement accuracy depends on the measurement range: 0.5 vol% + 3% measured value; 1 vol% + 3% measured value.
您是否需要能夠感應高達 100% 的CO 2濃度？如果是這樣，STC31 就是適合您的傳感器！Sensirion STC31 熱導率傳感器有兩個 CO 2測量範圍：0 到 25 vol%；和 0 到 100 vol%。測量重複性為 0.2 vol%，穩定性為 0.025 vol%/°C。測量精度取決於測量範圍：0.5 vol% + 3% 測量值；1 vol% + 3% 測量值。
Our breakout includes a separate SHTC3 humidity and temperature sensor; allowing the STC31 to deliver humidity-compensated measurements together with improved temperature compensation. The STC31 can compensate for atmospheric pressure too - which is handy if, like us, you’re up in the mountains!
我們的突破包括一個單獨的 SHTC3 濕度和溫度傳感器；允許 STC31 提供濕度補償測量以及改進的溫度補償。STC31 也可以補償大氣壓力 - 如果像我們一樣，你在山上，這很方便！
The STC3x sensor family is Sensirion’s series of Gas Concentration sensors designed for high-volume applications. The STC3x utilizes a revolutionized thermal conductivity measurement principle, which results in superior repeatability and long-term stability. This makes the STC31 a perfect choice for applications where reliability is key.
STC3x 傳感器系列是 Sensirion 的氣體濃度傳感器系列，專為大批量應用而設計。STC3x 採用革命性的熱導率測量原理，可實現卓越的可重複性和長期穩定性。這使得 STC31 成為可靠性至關重要的應用的完美選擇。
The outstanding performance of these sensors is based on Sensirion’s patented CMOSens® sensor technology, which combines the sensor element, signal processing and digital calibration on a small CMOS chip. The well-proven CMOS technology is perfectly suited for high-quality mass production and is the ideal choice for demanding and cost-sensitive OEM applications.
這些傳感器的出色性能基於 Sensirion 獲得專利的 CMOSens® 傳感器技術，該技術將傳感器元件、信號處理和數字校準結合在一個小型 CMOS 芯片上。久經考驗的 CMOS 技術非常適合高質量的批量生產，是要求苛刻且對成本敏感的 OEM 應用的理想選擇。
The STC31’s I2C address can be configured using the split-pad jumpers on the back of the board. The SHTC3’s I2C address is non-configurable; you will need a Qwiic Mux if you want to connect multiple sensors to the same bus.
STC31 的 I 2 C 地址可以使用電路板背面的分離焊盤跳線進行配置。SHTC3 的 I 2 C 地址是不可配置的；如果要將多個傳感器連接到同一總線，則需要Qwiic Mux。
As usual, our board includes a power LED, a pair of Qwiic connectors, I2C breakout pads and pull-up resistors. You can disable the LED and pull-ups if you need to by cutting the I2C jumpers on the back of the board.
像往常一樣，我們的電路板包括一個電源 LED、一對 Qwiic 連接器、I 2 C 分線焊盤和上拉電阻。如果需要，您可以通過切斷電路板背面的 I2C 跳線來禁用 LED 和上拉。
Our Arduino library contains example sketches for the Arduino IDE to get you up and running quickly. It can be downloaded through the Arduino Library manager: search for 'SparkFun STC3x' or it can be found in the Documents tab above.
我們的Arduino 庫包含 Arduino IDE 的示例草圖，可幫助您快速啟動和運行。它可以通過 Arduino 庫管理器下載：搜索“SparkFun STC3x”或者可以在上面的“文檔”選項卡中找到。
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
所述SparkFun Qwiic連接系統是我的生態系統I2C傳感器，執行器，防護罩和電纜，使原型更快，更容易出錯。所有支持 Qwiic 的電路板都使用通用的 1mm 間距、4 針 JST 連接器。這減少了所需的 PCB 空間量，極化連接意味著您不能將其連接錯誤。
