FILM TYPE WIND PRESSURE SENSOR AND CORRESPONDING WIRELESS SENSOR NETWORK

摘要

A film type wind pressure sensor is provided. The wind pressure sensor includes a top cover (1), a cavity (2) and a chassis (3). The film type wind pressure sensor also includes a circular air-tight film (4), the air-tight film (4) being arranged between the top cover (1) and the cavity (2), and electrically conductive fabric strain sensors (41) being arranged on the air-tight film (4) and connected with an external resistance measurement circuit. Three electrically conductive fabric strain sensors (41) are arranged in the center area of the air-tight film, and affixed to the inner surface of the air-tight film at included angles of 120 degrees. A wireless sensor network is provided. The sensitive element used for the film type wind pressure sensor and corresponding wireless sensor network is made of flexible material, which is suitable for high sensitivity fluid pressure monitoring in changing, open environments and in any direction.
