AN202478 - PSoC® 4 - Capacitive Liquid-Level Sensing

Last Updated: 
Mar 03, 2021
This application note shows how to use PSoC 4 devices, CapSense® technology, and capacitive sensors to measure the depth or presence of water-based liquids in nonconductive containers. Sensors located on or near the container exterior provide real-time reporting of liquid height or percent remaining without liquid contact. Options exist to use low-cost sensor materials while still providing high-precision measurements.
