摘要： A sensor device for detecting a flame comprises a carbon dioxide sensor for detecting a CO2 concentration, a fuel sensor for detecting the combustion of a fuel, an electrostatic charge variation sensor for detecting electrostatic charge variations generated by the flame, and a control unit. The control unit is configured to acquire a carbon dioxide signal indicative of the concentration of carbon dioxide, a fuel signal indicative of the fuel combustion, and an electrostatic charge variation signal indicative of a difference between the electrostatic charge variations detected by a first and a second electrode of the electrostatic charge variation sensor, determine a quantized signal based on the electrostatic charge variation signal, determine an aggregate datum based on the carbon dioxide signal, the fuel signal and the electrostatic charge variation signal, and generate, based on the aggregate datum, a flame signal indicative of the presence or absence of the flame.
