PROBLEM TO BE SOLVED: To provide an electronic nasal device capable of inspection without the use of a flowmeter, having stable air flow detection effect.SOLUTION: The electronic nasal device 100 includes at least a fan module 101, a gaseous molecule detection module 102, a control unit 103 and an output unit 104. The fan module includes at least a control device 101a and an air flow propelling mechanism 101b and actively sucks air so that the gaseous molecule detection module can detect it. The gaseous molecule detection module includes at least a gaseous molecule detection device 102a which forms a chemical compound to which a specified coating gaseous molecule can be connected on a converter. The control unit includes a motor controlling unit 103a and a gas detection device controlling unit 103b. The motor controlling unit includes a motor excitation circuit 103a1 and a counter electromotive force detection circuit 103a2. The gas detection device controlling unit includes a detection device excitation circuit 103b1 and a reaction detection circuit 103b2. |
