Use cases and implementation examples

Use Case 1: Industrial liquid management (humidifiers, robot vacuum cleaners)

[Use case overview]
Accurate detection of remaining liquid volume and flow rate is directly linked to the reliability and user experience of industrial and consumer equipment. Conventional mechanical sensors are prone to false detection due to bubbles or residue, which increases the need for frequent maintenance and the risk of malfunction. PSOC™ enables contactless, high-precision sensing, enabling smarter liquid management.
