Lid and cooking device

A lid comprises a cover body, a rotating member and a sensor. The cover body has a cover end in a closing direction. The rotating member comprises a rotating portion and a connecting portion. The rotating portion is rotatably disposed at the cover end, and the rotational axis of the rotating portion is perpendicular to the closing direction. The connecting portion is disposed at the rotating portion and extends perpendicularly to the rotational axis of the rotating portion. The sensor is disposed at the connecting portion and can rotate between an inoperative position near the cover end and the working position away from the cover end under the driving of the rotating portion. The lid is capable of accurately detecting and controlling the temperature inside a cooking device, and accommodating the sensor.
