Gravity:CCS811空氣品質感測器 可測量CO2、TVOC

CCS811空氣品質感測器能夠測量eCO2(equivalent CO2)和TVOC(Total Volatile Organic Compounds)濃度。可用于空氣測量應用,例如:空氣品質檢測、空氣淨化器、新風系統等。CCS811使用AMS獨有的微熱板技術,相比傳統的氣體感測器,功耗更低、預熱時間更短、體積更小。內部集成ADC和MCU,可以對資料進行採集、計算,並且通過IIC返回資料。

CCS811支援多種模式:每1秒、10秒、1分鐘、250毫秒測量一次以及休眠模式,這些模式在感測器測量期間進行了低功耗優化,因此CCS811適用于可擕式應用。CCS811支援濃度報警,當濃度超過用戶設置的閾值時,INT引腳就會觸發。

注意:該晶片對IIC進行了時鐘延展,有些控制器不支援時鐘延展,例如樹莓派。

Gravity: CCS811 Air Quality Sensor

Gravity: CCS811 Air Quality Sensor can measure the eCO2 (equivalent CO2) and TVOC (Total Volatile Organic Compounds) density. It can be widely used in many applications, such as air quality detection, air purifiers, ventilation system and so on. This CCS811 air quality sensor uses AMS’s unique micro-hot plate technology. Compared to conventional gas sensors, the heating wire is lower power consumption, heating faster, and smaller. Internally integrated ADCs and MCUs allow data to be collected, calculated and returned via IIC. The CCS811 supports a concentration alarm, which is triggered when the concentration exceeds the user-set threshold.

The CCS811 air quality sensor supports multiple modes, such as detect in every second, in every 10s, in every one minute, in every 250ms and sleep mode. These modes are optimized for low power consumption during the sensor measurement, so the CCS811 is also suitable for portable applications.

NOTE: The chip has stretched the clock in IIC. So, it is not compatible with some controllers, such as Raspberry Pi.
