This is a gas sensor that can detect a wide range of Volatile Organic Compounds (VOCs) and H2 and is intended for indoor air quality monitoring. When connected to your microcontroller (running our library code) it will return a Total Volatile Organic Compound (TVOC) reading and an equivalent carbon dioxide reading (eCO2) over I2C.
這是一種氣體傳感器，可以檢測多種揮發性有機化合物（VOC）和H2，旨在用於室內空氣質量監測。當連接到您的微控制器（運行我們的庫代碼）時，它將通過I2C返回總揮發性有機化合物（TVOC）讀數和等效的二氧化碳讀數（eCO2）。
The SGP30 has a 'standard' hot-plate MOX sensor, as well as a small microcontroller that controls power to the plate, reads the analog voltage, tracks the baseline calibration, calculates TVOC and eCO2 values, and provides an I2C interface to read from. Unlike the CCS811, this sensor does not require I2C clock stretching.
SGP30具有一個“標準”熱板MOX傳感器，以及一個小型微控制器，可控制板的電源，讀取模擬電壓，跟踪基線校準，計算TVOC和eCO2值，並提供I2C接口以讀取。與CCS811不同，此傳感器不需要I2C時鐘延長。
This part will measure eCO2 (equivalent calculated carbon-dioxide) concentration within a range of 400 to 60,000 parts per million (ppm), and TVOC (Total Volatile Organic Compound) concentration within a range of 0 to 60,000 parts per billion (ppb).
該部分將測量 百萬分之400至60,000（ppm）範圍內的eCO2（等效計算二氧化碳）濃度，以及測量 十億分之0至60,000 ppb（ppb）之間的TVOC（總揮發性有機化合物）濃度。
Please note, this sensor, like all VOC/gas sensors, has variability and to get precise measurements you will want to calibrate it against known sources! That said, for general environmental sensors, it will give you a good idea of trends and comparison. The SGP30 does have built in calibration capabilities, note that eCO2 is calculated based on H2 concentration, it is not a 'true' CO2 sensor for laboratory use.
請注意，該傳感器與所有VOC /氣體傳感器一樣，具有可變性，要獲得精確的測量結果，您將需要針對已知來源對其進行校準！也就是說，對於一般的環境傳感器，它將為您提供趨勢和比較的好主意。SGP30確實具有內置的校準功能，請注意，eCO2是根據H2濃度計算得出的，它不是實驗室使用的“真正” CO2傳感器。
Another nice element to this sensor is the ability to set humidity compensation for better accuracy. An external humidity sensor is required and then the RH% is written over I2C to the sensor, so it can better calculate the TVOC/eCO2 values.
該傳感器的另一個優點是能夠設置濕度補償以實現更高的精度。需要使用外部濕度傳感器，然後將RH％通過I2C寫入傳感器，因此它可以更好地計算TVOC / eCO2值。
