Development of tire condition monitoring system (TCMS) based on MEMS sensors

The design and demonstration system of tire condition monitoring system (TCMS) is presented. MEMS sensors such as pressure sensor, accelerometer, and temperature sensor are used to measure pressure, vibration, and temperature of the tire. The characteristics of the sensors were observed. Based on the sensors output characteristics, necessary amplification schematic was made for the demonstration system. For the data acquisition, National Instruments educational laboratory virtual instrumentation suite (NI ELVIS) bench-top workstation is used. The information obtained was passed to a computer for human interface.
