Tire sensors, also known as tire pressure monitoring systems (TPMS), are devices that are used to monitor the air pressure in a vehicle's tires. These sensors are located within the tires themselves and are designed to alert the driver when the pressure in one or more tires is too low.The sensors are typically located within the valve stem of the tire. The valve stem is the small protrusion that sticks out of the rim of the wheel and is used to inflate and deflate the tire. The sensor is usually a small electronic device that is inserted into the valve stem and is sealed with a rubber cap to keep out dust and moisture.Each sensor is equipped with a battery and a small transmitter that sends a signal to a receiver located in the vehicle. The receiver is usually located in the vehicle's dashboard or center console and is connected to the vehicle's onboard computer. The computer then interprets the signal from the sensor and displays the tire pressure information on the dashboard or a central display in the vehicle.When the air pressure in one or more tires is too low, the sensor sends a signal to the vehicle's computer, which in turn sends a warning signal to the driver. This warning can be in the form of a visual or audible alert, or a combination of both. The driver can then take the necessary steps to inflate the tire to the correct pressure, ensuring that the vehicle is operating safely.In summary, tire sensors, or TPMS, are devices that are used to monitor the air pressure in a vehicle's tires. They are typically located within the valve stem of the tire and are designed to alert the driver when the pressure in one or more tires is too low. The sensors send signals to the vehicle's computer which in turn sends warning signals to the driver. These sensors play a vital role in ensuring that the vehicle is operating safely by alerting the driver when the air pressure in the tires is too low, and need to be checked or filled.
