The ams company’s environmental evaluation kits target designers wanting to integrate a compact, low-power indoor air quality (IAQ) monitoring circuit into portable devices such as smartphones, wearables, and home/building automation devices. The CCS811-LG_EK_ST kit combines two environmental sensors. The CCS811 gas sensor system-on-chip (SSoC) uses low-power sensor technology to detect volatile organic compounds (VOCs) in an indoor environment. The CCS801-DF_EK_ST kit features a CCS801 VOC gas sensor with an external MCU instead of a CCS811.The ENS210 relative humidity and temperature sensor IC achieves very high accuracy. The CCS811 kit includes an embedded microcontroller that runs ams algorithms to convert raw sensor readings into equivalent total VOC (ppb) and equivalent CO2 (ppm) measurements. These can be used to provide a measure of IAQ. The measurements of relative humidity and temperature taken by the ENS210 allow the system to adjust the digital output of the CCS811 by compensating for changes in the ambient environment.
Used together with the ams algorithms, the CCS8x1 and ENS210 sensors provide a complete solution for IAQ monitoring which consumes little power and has a very small board footprint, making it suitable for a wide range of portable applications. The two evaluation kits provide a simple way to configure and operate the sensor system, and to log and view its measurements. Each kit consists of a sensor board with an I2C digital interface, a USB-to-I2C board and a USB cable. The board is supported by a free graphical user interface for a PC based on the Windows operating system. For more information, visit http://www.ams.com/gas-sensors/CCMOSS-evalkits
