Abstract

A new kind of infrared and ultraviolet integrated fire sensor is proposed. The sensor was fabricated using ferroelectric polymer technology based on the pyroelectric effect in PVDF films. A principle model of the fire sensor is proposed, furthermore the light-thermal-electrical conversion of the sensor are studied. The design and construction of the fire sensor has been discussed. The proximity sensor, originally integrates the infrared sensing element and ultraviolet sensing element together, thus to improve the detecting accuracy and the dependability of the whole detecting system. The device preparation process is also described. Theoretic parameters and the function test results manifest that this new kind fire sensor has much better sensing properties and detecting sensitivity.
