The Würth Elektronik range of sensors provide advanced sensing capabilities to any embedded application. The built-in digital interface enables easy integration with any of the most commonly used host MCUs through industry standard serial communication interfaces like I²C. This also allows complete configuration and control of the sensor via software running on the host MCU.
The Sensors Software Development Kit (SDK) is a set of software tools that enable quick software integration of Würth Elektronik eiSos sensors to application software on the host MCU. It consists of a set of platform-independent drivers for the sensors and sample applications developed on the Raspberry Pi platform written in C.
