This reference design, which uses FDC1004EVM, provides robust and accurate capacitive-based liquid level sensing. TIDA-00317 demonstrates the sensor design and configuration setup to mitigate parasitic capacitance interference from the system environment.
- Liquid-level sensing using capacitive sensing technology
- Reduces parasitic interference from the system environment
- Rigid-flex circuit allows the sensors to be placed on various surface shapes
- Liquid height resolution of <1 mm
- Includes the environmental reference sensor to help compensate for environmental changes
- Developed to be paried with FDC1004EVM and FDC1004EVM GUI
