The invention discloses a tire pressure monitoring sensor installed on a wheel hub of an automobile. The tire pressure monitoring sensor comprises a sensor with an independent power supply module, wherein the sensor is connected to an inflation valve through a fastener, at least can collect the tire pressure, the tire temperature, and vehicle vibration, and can send tire information and/or an alarm signal through wireless communication. The tire pressure monitoring sensor further comprises an inflation valve cap with an alarm module fixedly sealed and fixedly installed on the inflation valve, wherein the alarm module has an independent power supply module and is capable of receiving sound and/or light warning generated from alarm information sent by the sensor. At least one light hole is arranged in the center of the top end of the inflation valve cap, and a plurality of buzzing holes are arranged at the edge of the top end. The invention further provides a tire pressure monitoring system adopting the tire pressure monitoring sensor. The tire pressure monitoring sensor in the invention can monitor the tire state when an automobile is shut down; a safety corner of monitoring the tire state by a tire pressure monitoring sensor in the prior art when an automobile is shut down is filled up; and the safety of driving an automobile is improved.
