abstract = "The presented method outlines a low-cost rotating test platform for calibrating and measuring the sensitivity of accelerometers. Traditionally, accelerometers are tested and calibrated using heavy-duty shaking devices, which involve numerous cables and are challenging to maintain. This method leverages the centripetal force generated by the rotating platform to apply a fixed acceleration at set revolutions per minute (RPM). A major advantage of this innovation is the use of wireless technology to transfer the accelerometer data to a computer, eliminating the need for lengthy cables. The rotating platform can generate different accelerations at varying distances along the radius by spinning at different RPMs. The proposed method employs a circular platform that rotates in a controlled manner using a motor at desired RPMs. The output voltage from the accelerometer is read using a microcontroller and sent wirelessly to a computer for further analysis. The collected data can be processed to determine the accelerometer's sensitivity, and the proposed method can test multiple sensors simultaneously.",
