Hello,
I'm working on a project were I need to measure or detect the waterlevel in an adjacent case where water is flowing. The intention is to create a pcb with a Capsense pattern and place is to wall of this case and use one of the Cypress MCU to do the algorithm. But I have no experience with this and don't know which MCU is best for this application.
We have a prototype that works with a STM32 MCU, but the accuracy is not good enough. That is why we want to switch to one of Cypress MCU.
My questions:
- Which Cypress MCU is best for my project?
- What kind of pattern for the Capsense sensor is best for my application?
If needed I can provide the Capsense sensor design pattern we use at the moment.
Thank you.
Kind regards,
Sergio van Vliet

Hi @SergiovanVliet ,
Please refer to the PSoC 4 Liquid Level Sensing Application Note: https://www.infineon.com/dgdl/Infineon-AN202478_PSoC_4_Capacitive_Liquid_Level_Sensing-ApplicationNo...
The application note suggests the use of CY8CKIT-022 kit for prototyping the LLS model.

And for the device selection you could go with any of the following device families based on your application requirements.
- PSoC4000S - For Entry Level latest CapSense Device
- PSoC4100S
- PSoC4100S Plus
You can refer the respective Datasheet's Ordering information section for more details for Pin Package and functionalities in different devices.
