Abstract


The paper emphasizes the conceptual design and theoretical evaluation of an Internet of Things (IoT)-enabled torque measurement system for vehicular drivetrains. The proposed system integrates cost-efficient components, including a Wemos D1 Mini ESP8266 microcontroller, BF350-3HA-E strain gauges, and an HX711 load cell amplifier, to enable real-time monitoring of rotational forces. Calibration is performed using a dynamometric wrench compliant with ISO 6789:2017 standards, covering a torque range of 5–50 Nm. The system is theoretically expected to achieve ±1.5% accuracy at a cost below 30 euros. The novelty lies in its ability to combine affordability, portability, and precision with IoT-enabled intelligent measuring and control capabilities. This work offers a scalable solution for cost-sensitive automotive applications, with potential for experimental validation and broader adoption.
