MIKROE AIR QUALITY 3 CLICK (MIKROE-2953) – eCO₂ & TVOC Air Quality Sensor Board, I²C

MIKROE AIR QUALITY 3 CLICK (MIKROE-2953) – eCO₂ & TVOC Air Quality Sensor Board 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. The Click board™ is also equipped with a temperature compensating element, which allows for increased measurement accuracy.

This Click board™ outputs processed values for the equivalent CO2 levels (parts per million - ppm) and TVOC (parts per billion - ppb), based on raw gas readings, processed by the internal MCU. The values can be directly accessed via the I2C bus, which saves the software development time, allowing faster time to market. These features make Air quality 3 clicks a perfect solution for a wide range of both portable and stationary applications for measuring and monitoring the air quality in offices, storage areas, for home and building air conditioning automation and similar applications that require a reliable, low power eCO2 and TVOC level measurements.

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.

Overview:

Applications: A perfect solution for various air conditioning systems, ventilation systems, and other IoT applications where accurate, detailed, and reliable air quality readings are required.
