Land transportation, especially motorized vehicles, is still the main mode of transportation used by the Indonesian people. Along with the times, the number of motorized vehicles continues to increase. In 2021, the number of motorized vehicles in Indonesia has reached more than 140 million vehicles. However, with the increase in the number of motorized vehicles, the number of accidents that occur has also increased. In 2019, the number of motor vehicle accidents that occurred reached more than 116 thousand cases and 80% of accidents that occurred on toll roads were caused by lack of tire pressure. This shows that the safety and awareness of vehicle users regarding tire pressure is under minding. Tire pressure monitoring can be a solution to reduce these cases. Tire pressure monitoring is an air pressure monitoring device that can deliver realtime air pressure information on car tires to vehicle users. Tire pressure monitoring products can be easily found in the market. However, in the Indonesian market, these products are still dominated by foreign products. Further development can be started from proof of concept in the reverse engineering stage as the first step in product manufacturing. The prototype of tire pressure monitoring is designed in this research by using a pressure sensor that has a strain gauge in it and a bluetooth-based information delivery system. The analysis shows that the tire pressure monitoring prototype can work according to its function and the prototype calibration process produces a linear equation y = 0,02x. In the equation, y is ???????????????? ???? ???????????????????????????????? (V) and x is pressure (Psi). The circuit system of tire pressure monitoring prototype and how tire pressure monitoring prototype works are explained in this research.
