ENS210 Evaluation Kit

The ENS210 Evaluation Kit is a combination of an ENS210 flex rigid PCB and a micro-USB-to-I²C convertor. The evaluation kit connects to a Windows PC via USB port and the sensor is powered via the micro-USB- to- I²C convertor. It can be controlled by a Windows PC based application, which demonstrates the relative humidity and temperature values measured by the sensor. The PC application can also be used for logging of sensor data as well as to monitor the I²C transaction. The evaluation kit can also be used for quick integration into the end customer’s application.

The ENS210 evaluation kit comes with an extensive set of documentation such as a user manual, application notes, reference drivers for easy design in.
