Rancang Bangun Kalibrator Pengukur Panjang Menggunakan Sensor HCSR-04 Berbasis ESP 8266

Abstract

This tool is designed to provide a practical and efficient solution for measuring length with high precision, which is expected to be used in various industrial and educational applications. The HC-SR04 ultrasonic sensor was chosen for its ability to measure distance with fairly good accuracy, while the ESP8266 module was used to enable wireless connectivity and real-time data processing. The test results show that this tool is able to measure length with a sufficient level of accuracy, even though there is an error of 1 cm. The average calibration value produced by this tool exceeds 1 cm compared to the standard used. Nevertheless, this tool still provides ease of use, especially in applications that require high mobility and long distance data access. In conclusion, the design of the HC-SR04 and ESP8266 sensor-based length measuring calibrator succeeded in fulfilling the research objectives by producing an accurate tool, efficient, and easy to use.
