【应用笔记】优化的准则STM8T14x电容式传感器与接近检测 AN3150 Application note Guidelines to optimize proximity detection with STM8T14x capacitive sensors Introduction The STM8T14x capacitive sensors open up a new dimension in capacitive sensing by detecting user proximity up to a few cm. This is a key feature for many end-applications such as personal navigation devices (PNDs) or stove tops which are equipped with backlighting that switches on when a user is detected. Proximity detectors are also implemented in white goods, automotive devices, palm……
