  "textContent": "An external TPMS sensor for heavy-duty trucks comprises a helical antenna and a 1225 cell, and is installed outside a tire of a vehicle; and system power consumption is reduced by increasing the communication rate of the TPMS sensor, and/or decreasing the sampling period, and/or decreasing the number of data frames transmitted every time, and/or decreasing RF output power, and/or disposing an LNA circuit at an input terminal of a corresponding receiver antenna. The requirement of the TPMS sensor for a long service life is met by reducing system power consumption; the helical antenna, the matching network, and the 5 dBm chip for outputting power are used to realize miniaturization of the TPMS sensor; and the 1225 cell is used, which, compared with traditional TPMS sensors, allows the diameter of the TPMS sensor to be reduced by about 8 mm and the weight of the TPMS sensor to be reduced by over ⅓, such that miniaturization of the TPMS sensor is further realized.",
