Abstract

This utility model relates to a smart wood surface panel system, including a capacitive touch-sensitive film, a pressure sensing circuit, a temperature sensing circuit, and an MCU. The capacitive touch-sensitive film is disposed on the surface of the smart wood surface panel and is used to detect touch operations and output touch signals. The pressure sensing circuit is disposed on the panel and includes a pressure sensor, a first operational amplifier, and a first low-pass filter. The pressure sensor senses pressure and converts it into an electrical signal, which is amplified and filtered to output a stable pressure sensing signal. The temperature sensing circuit includes a temperature sensor, a second operational amplifier, and a second low-pass filter, used to sense temperature changes and output a stable temperature sensing signal. The MCU is connected to the first three components and receives various signals. This utility model uses a pressure sensor for secondary touch confirmation, reducing the risk of accidental touches, and the hardware design of the pressure and temperature sensing circuits improves pressure detection accuracy and system environmental adaptability.
