Abstract
A tire pressure detection device includes a chip, a Bluetooth receiving circuit, a Bluetooth antenna, a battery, an LF trigger coil, a power switch, an LF trigger switch and a monitor respectively connected to a case. The Bluetooth receiving circuit is electrically connected to the chip and the Bluetooth antenna. The LF trigger coil, the power switch, the LF trigger switch and the monitor are respectively connected to the chip. A user holds and inserts the tire pressure detection through a double rims. The chip sends an LF signal via the LF trigger coil to activate a Bluetooth tire pressure detector at the inner rim to detect tire pressure. A pressure signal of an inner tire is sent to the chip via the Bluetooth antenna and the Bluetooth receiving circuit. The chip displays the tire pressure of the inner tire on the monitor to be checked by the user.
