A flux sensor and a gas valve device with the same are provided to maintain performance regardless of temperature change by sensing gas flux using the temperature change. A flux sensor includes first and second thermistors(TH1,TH2) and first and second power supplies(VCC,VGND). The first thermistor is installed inside a gas supply pipe and connected to the first power supply. The second thermistor is interposed between the first thermistor and the second power supply and connects the first thermistor and the second power supply. Resistance of the first thermistor is changed according to gas flux. Voltage according to the gas flux is detected through both sides of the first thermistor. |
