HOW DOES IT WORK?
Diff Press 2 Click as its foundation uses the SDP31-500PA, a highly versatile differential pressure sensor designed for high-volume applications from Sensirion. It builds on the next-generation CMOSens® sensor chip at the heart of Sensirion's new differential pressure and flows sensing platform. It features fast measurement speed, excellent accuracy, and long-term stability, has no zero-point drift, and offers an ultra-low power consumption, making the SDP31-500PA the perfect choice for applications where accurate and reliable pressure monitoring is essential.
The SDP31-500PA is very flexible regarding measurement speed. This flexibility allows for optimizing the sensor's performance to a specific application and for adapting the sensor to different use cases. For example, the sensor detects the smallest and quickest changes in one use case, whereas, in another mode, the sensor can measure in larger intervals while consuming only little energy.
Diff Press 2 Click communicates with MCU using the standard I2C 2-Wire interface to read data and configure settings, supporting Fast Mode up to 400kHz. Besides, the SDP31-500PA allows choosing the least significant bit (LSB) of its I2C slave address using the SMD jumper labeled ADDR SEL. It also possesses an additional interrupt signal, routed on the INT pin of the mikroBUS™ socket labeled as INT, indicating when a specific interrupt event occurs, such as indicating whether new measurement results are available.
This Click board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the I2C communication lines properly. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
