Automotive instrumentation is an important process to guarantee quality and safety for the drivers and passengers of vehicles. At the same time, it is a time‐consuming task, because engineers must setup the system, which includes the passing of cables through the vehicle and the configuration of equipments. A wireless automotive instrumentation system can certainly help on reducing the instrumentation time and its cost. However, it may incur in errors due to the wireless communication between sensors and the base station. In this study, the authors propose a low‐cost wireless monitoring system for automotive instrumentation. They compare the proposed system with two commercial instrumentation equipments in terms of features, cost, and precision for monitoring the engine speed. The results indicate that the proposed wireless monitoring system delivers similar performance, but at a lower cost (up to 1114 times cheaper).
