The present invention provides a tire pressure sensor, including a housing, a PCBA installed within the housing, a power supply device installed within the housing and electrically connected to the PCBA, and an antenna connected to the PCBA. The antenna is wrapped around the PCBA, and at least one turn of the antenna is wrapped around the PCBA. The antenna is wrapped around the PCBA, and a length of the antenna may be increased within a limited internal space of the tire pressure sensor. An effective space of the antenna may be particularly enlarged by wrapping the antenna around the PCBA, thereby improving efficiency of the antenna, increasing a signal transmitting distance of the antenna, and enhancing signal transmission stability and anti-interference capability of the antenna, so that an automobile receiver can stably receive, in real time, information such as internal pressure and a temperature of the tire detected by the PCBA, better implementing real-time monitoring of the air pressure, the temperature, and the like within the tire.
