The Gravity CCS811 Air Quality Sensor is a high - performance device. It can accurately measure eCO2 (equivalent CO2) and TVOC (Total Volatile Organic Compounds) density. This sensor is widely applicable in various fields like air quality detection, air purifiers, and ventilation systems. It uses AMS's unique micro - hot plate technology. Compared with traditional gas sensors, it features lower power consumption, faster heating, and a smaller size. With internally integrated ADCs and MCUs, it can collect, calculate, and return data via IIC. It also supports a concentration alarm, which goes off when the concentration surpasses the user - set threshold. The CCS811 offers multiple operation modes, including detection every second, every 10 seconds, every minute, every 250 milliseconds, and a sleep mode. These modes are designed for low power consumption during measurement, making it ideal for portable applications. Note that the chip stretches the clock in IIC, so it's not compatible with some controllers such as Raspberry Pi. Key features include a short warm - up time, low power consumption, highly integrated MCUs and ADCs, and an IAQ threshold alert. It can be used for air quality detection in cars, indoor spaces, in air purifiers, smart homes, and ventilation systems. You can find the product wiki for more details.
Using the Gravity CCS811 Air Quality Sensor is quite easy. First, make sure it's properly connected to your device. Check that it's not one of the incompatible controllers like Raspberry Pi. You can choose the operation mode according to your needs. For example, if you want continuous real - time data, select the one - second detection mode. If you're aiming for power savings, the sleep mode or longer - interval detection modes are good options. When the concentration of eCO2 or TVOC exceeds the threshold you've set, you'll get an alarm. Regarding maintenance, keep the sensor in a clean environment. Avoid exposing it to extreme temperatures or high - humidity conditions for a long time.
