Standard or Custom Solution?
Standard solution already covers an extensive pressure range, however, this might not be enough for some specific application.For example, an application requires a pressure range from 0 to 4 bar where the system operates on 3.3V supply voltage. Within our standard solutions, the pressure range of -1 to 10 bar would meet the pressure requirement, but it cannot work on 3.3 V supply voltage.With our individualization services, we are able to provide a sensor with operating pressure 0 to 4 bar and supply voltage 3.3 V. Along with the pressure range and supply voltage, many other parameters like communication interface, ADC resolution etc. can also be individualized. Packaging variants with barbed nozzles are also available for the applications where the pneumatic tubes need to be attached directly to the sensor.

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.Find more information in the Sensor SDK Manual.
