Product name
Evaluation Kit for CCS801

The CCS801 is an analog VOC sensor for detecting VOCs (volatile organic compounds) for monitoring indoor air quality. The CCS801 Evaluation Kit is a combination of a CCS801 shield and a USB to I²C dongle. The evaluation kit connects to a Windows PC via USB port and the sensor is powered via the USB connector. It can be controlled by a Windows PC based application, which demonstrates the sensor output and calculated TVOC and equivalent CO2 values. In addition, this kit 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 CCS801 evaluation kit comes with an extensive set of documentation such as a quick start guide, a user manual, application notes and reference drivers for easy design in etc.

Product name
USB-I²C Dongle

The USB-I²C dongle is a small device with a form factor much like a USB flash memory. It can be inserted in a PC and then allows the PC to act as an I²C master. The dongle is used in the evaluation kit of several environmental sensors of ams. Here you find a user manual, the Windows driver (Windows 7 and 8, not needed for 10), and the firmware for the (micro controller on the) dongle.

Product name
ENS Dashboard

The ENSDashboard is a Windows application that supports monitoring and logging of sensor measurements.
