AN92239 - Proximity Sensing with CapSense®
A proximity sensor detects the presence of a nearby object without any physical contact. Cypress’s CapSense devices support self-capacitance based proximity sensing and can achieve up to a 30-cm proximity-sensing distance. This application note explains how to:
- Design a proximity sensor and tune the CSD parameters to achieve large proximity-sensing distances
- Tune the CSD parameters for a proximity sensor to achieve liquid tolerance
- Implement proximity-based gesture detection
- Implement the wake-on-approach feature to reduce the power consumption of the device
Dear valued customer,
Thank you for choosing our products. They come with all the know-how and passion that our engineers have put into it. As you probably already know, Cypress is now Infineon. This is a major step for our company, but also for the good of you.
