General Description
CCS811 is a low-power digital gas sensor solution, which integrates a gas sensor solution for detecting low levels of VOCs typically found indoors, with a microcontroller unit (MCU) and an Analog-to-Digital converter to monitor the local environment and provide an indication of the indoor air quality via an equivalent CO2 or TVOC output over a standard I2C digital interface.
This product suits for the following applications:
- Smartphones and accessories
- Air cleaners and purifiers
- Appliances (white goods)
- Home controllers
- Smart thermostats

Evaluation Kit for CCS811
CCS811EvalKit
The CCS811 is a digital VOC sensor for detecting VOCs (volatile organic compounds) for monitoring indoor air quality. The CCS811 Evaluation Kit combines a CCS811 sensor board and an USB to I²CIO board and connects directly to a Windows PC via USB port. It can be controlled by a Windows PC based application, which demonstrates the sensor output with calculated values for TVOC and equivalent CO2. In addition, this kits demonstrates the relative humidity and temperature values measured by the ENS210 sensor and uses this information to compensate for environmental changes during VOC detection. The PC application can also be used for logging of sensor data as well. The evaluation kit can also be used for quick integration into end customer’s application. The CCS811 evaluation kit comes with an extensive set of documentation such as a quick start guide, an user manual, and application notes etc. for easy design in.
Windows ENS Dashboard
ENSDashboard
The WinDashboard is a Windows application that supports monitoring and logging of sensor measurements. It also supports firmware updates for those sensor kits that have an embedded micro controller. The WinDashboard is used in the evaluation kit of several environmental sensors of ams. Here you find the user manual and a redirect to the auto-installer/auto-updater of the WinDashboard.
