Pressure sensing device, pressure sensing system using the same, and pressure sensing switch using the same

摘要

To provide a pressure detection device, a pressure detection system using the same, and a pressure detection switch using the same.A pressure detection device includes an elastic tube body and a pressure sensor. The elastic tube body has a chamber and an opening connected to the chamber. The pressure sensor is fitted into the opening of the elastic tube body and detects the pressure change in the chamber of the elastic tube body subjected to the external force. Due to the structural features described above, the pressure detection device can be used in special environments requiring measures against water or dust. On the other hand, the pressure detection device is incorporated in a bed mat or a sheet mat, and not only can detect a change in the physiological state of the user by a signal processing device, it is incorporated in the floor mat of the entrance, and attention is paid to people's coming and going by lighting or sound effect It can be evoked. Therefore, the structure of the pressure detection device can be simplified, the practicality can be improved, and the application range can be expanded.BACKGROUND OF THE INVENTION
