Air quality 3 click is the air quality measurement device, which is able to output both equivalent CO2 levels and total volatile organic compounds (TVOC) concentration in the indoor environment. The Click board™ is equipped with the state-of-the-art air quality sensor IC, which has an integrated MCU and a specially designed metal oxide (MOX) gas sensor microplate, allowing for high reliability, fast cycle times, and a significant reduction in the power consumption, compared to other MOX sensor-based devices.
How Does It Work?
Air quality 3 clicks is equipped with the CCS811, an advanced ultra-low power digital gas sensor for monitoring the indoor air quality (IAQ), from ams. This IC consists of an analog section consisting of a MOX gas sensor, based on ams unique micro-hotplate technology which allows high reliability, fast cycle times, and very low power consumption; and the digital section, which consists of an embedded microcontroller (MCU) and an analog to digital converter (ADC). The CCS811 sensor IC employs advanced algorithms to calculate the raw sensor data and output the equivalent CO2 and TVOC values. It utilizes the internal MCU for this purpose, reducing the payload on the host MCU.
