GAS SENSOR FOR VOLATILE BASIC NITROGEN, AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A gas sensor for measuring volatile basic nitrogen gas and a manufacturing method thereof are provided to improve sensitivity and selectivity for volatile basic nitrogen gas. CONSTITUTION: A gas sensor for measuring volatile basic nitrogen gas comprises a substrate(10), an electrode(20), a detecting film(40), and a heater(30). The electrode is formed on the front surface of the substrate. The detecting film is made of TiO2/WO3 nano powder and covers the electrode. The heater is formed on the rear surface of the substrate.
