摘要： PROBLEM TO BE SOLVED: To provide a tire pressure sensing device, capable of sensing an appropriate air pressure at always, with no damage or falling at attaching/detaching operation of a tire. SOLUTION: A board type sensor device 2, which is arranged inside a tire and connected to a sensor antenna 3, includes a semiconductor integrated circuit chip 9 composed of a pressure sensor 16, a temperature sensor 17, a conversion circuit which converts the electrical signals that the sensor measures into a signal for wireless transmission, and a rectifying circuit 15 for generating a drive current. A control processor 4, which is disposed to a car body, comprises an antenna 5 for transmitting/receiving signals from the board type sensor device 2, and a control circuit 33 which controls transmission radio waves and compensates the received signal for temperature to calculate a tire air pressure value. So the board type sensor device 2 is small and thin, preventing damages or falling at attaching/detaching of a tire 52, while an appropriate air pressure is always stably detected.
