FIELD: transport.
SUBSTANCE: proposed device comprises wheel acceleration detector, gravity acceleration component detector and mechanism to transmit tire air pressure data by wireless signal when gravity acceleration signal reached predetermined magnitude. This device is configured to set sampling period or cycle proceeding from the wheel centrifugal acceleration in centrifugal direction and to detect the magnitudes of gravity acceleration component of centrifugal acceleration in every preset sampling period.
EFFECT: decreased power consumption by air pressure transmitter and higher precision of related data transmission.
