Electronic device for detecting an air flow

An onboard electronic device for detecting an air flow, the electronic device comprising:

• a support allowing a passage of the air flow;
• at least one sensor disposed in the passage of the air flow,
• wherein each sensor comprises at least one pair of platelets, each platelet comprising an RTD and having one end fixed to the support, another end of said platelet being free and overlapping the free end of the other platelet of the pair of platelets, at least one platelet being flexible so as to form a switch for an electrical circuit,
• wherein an air flow with a speed higher than a predetermined speed being able to make the sensor go from a first state, corresponding to the switch being closed, in which the free ends of the overlapping platelets are in contact, to a second state, corresponding to the switch being open, in which said contact is broken,
• the electronic device further comprises a first detection module allowing, for each sensor, an electrical resistance of the electrical circuit of the sensor to be measured between two predefined terminals, the electrical resistance measured corresponding to the RTDs of the sensor connected in parallel when the switch is closed, or to only one of the RTDs of the sensor when the switch is open.
