Abstract
This paper presents the tire pressure monitoring system (TPMS) by using the system on chip (SoC) mixed signals with the help of Bluetooth transmission and in advantage of low power consumption design. This is to monitor the variations in temperature and pressure of the vehicle’s tire, and the TPMS system is involved. It improves the driver’s safety by automatically detecting the tire pressure and temperature and then warning signal is sent to driver to take a measure, which prevents from accident. The proposed system of tire pressure monitoring system using SoC increases the speed of indication time to the driver by using mixed signals. The inflation of the tire can be avoided by preventing from high temperature and high pressure. Limitation of temperature and pressure in the previous system is also elongated i.e. temperature from 40℃ to 125℃ and pressure from 0 to 750 Kpa. Sensors, wireless communication (Bluetooth dongle) and SoC unit are used to design the low power TPMS. Quantitative results are taken and the analogy between temperature and pressure is also verified. The tested results proved by need of the practical system. Signal conditioning voltage and SoC unit is the trace for low power design TPMS. Finally, the performance of the system is tested and executed by using proteus software given as a real time application.

Summary
One of the main reasons for serious traffic accidents is bursting or inflation of tires. Many new high-end vehicles list tire pressure monitoring as part of standard equipment In the past this was typically achieved by enhancing the capabilities of the Antilock Braking System (ABS) using differential (wheel-to-wheel) rotational speed measurement as a criteria to check if one tire was under inflated [2]. In direct TPMS, the difference between the speeds of the tires is compared through an Antilock Braking System (ABS) wheel speed sensor system [12] The disadvantage of this system is that it cannot able to work if vehicle is moving with a speed above 100 km or if two tires are under-inflated. The one is based on the pressure sensor, and it’s called as direct-TPMS This system makes use of pressure and temperature sensor which are installed in each tire; this will directly measure the tire’s pressure and temperature, it displays the monitored level in each tire [10]. The tire pressure monitoring systems (TPMS) based on Bluetooth or wireless technology discussed here can be used in wide range of applications
