本装置是一个以HT46R71D 为主芯片，配合传感器组成的汽车轮胎气压检测装 置，最终取高三位有效值于LCD 显示，有四种显示单位供切换（Psi、Bar、Kpa、 Kgf/cm2）。本装置仅为参考范例，使用时，为提高准确度，建议多量测些组数 据来构建Sensor Output Voltage - Discharge Time (V-T)表格，并作相应校准。-This device is a HT46R71D-based chips, with sensors detecting vehicle tire pressure devices, and ultimately take the high-three RMS in LCD display, there are four types of display units for switching (Psi, Bar, Kpa, Kgf/cm2). Only reference to an example of the device, when used to improve the accuracy of the proposed多量measured set of data to build more Sensor Output Voltage- Discharge Time (VT) forms, and the corresponding calibration.
