1.1 Introduction
This evaluation board provides a straightforward and cost-effective option to test and evalu-
ate the differential pressure sensors from Würth Elektronik eiSos. It can be connected to the
host controller (e.g. Arduino) using I
2
C interface pins. Through hole pin header connections
allow the board to be mounted on a bread board.
The differential pressure sensor (Part No: 25131308xxx01) is a MEMS based 15-bit piezo-
resistive pressure sensor with a digital I
2
C and an analog interface. The sensor evaluation
board is available in five pressure measurement ranges from 0.1 kPa to 1000 kPa (See
table
1
. In addition to the sensor and decoupling capacitors, the evaluation board consists
of a mounted adapter with two nozzles. Pneumatic tubes can be connected to the nozzles.
Barbed nozzle design improves the overall mechanical stability of the connection.
