Thank you for your interest in the CapSense
®
Liquid Level Sensing Shield Kit (
). This
kit is intended to demonstrate the Liquid Level Sensing (LLS) capabilities of the CapSense technol-
ogy in Cypress’s PSoC
®
4 products.
This kit supports the following liquid level sensing features:
■
Non-contact measurement of liquid levels from sensors located on the exterior of the non-
conductive liquid container. Avoids contamination and cleaning issues found with mechanical and
contact sensors, simplifying industrial design and improving user experience.
■
Supports two different sensor patterns. A two sensor ‘Backgammon’ shaped pattern provides
liquid level sensing at a low cost point while a multi sensor ‘Segmented’ pattern provides
increased accuracy that can be optimized for each design by varying the number and shape of
sensors.
This kit guide provides details on the kit contents, hardware, schematics, and BOM. See Code
