Project Overview
Measure-X represents a breakthrough in portable measurement technology, combining multiple sensor technologies with advanced filtering algorithms to deliver professional-grade accuracy in a compact, wireless package.
The device integrates a VL53L0X time-of-flight distance sensor with an MPU6050 inertial measurement unit, processed through sophisticated Kalman and Complementary filters to achieve remarkable precision. The ESP8266 microcontroller provides wireless connectivity and real-time data processing, while an OLED display offers immediate visual feedback for measurement verification.
The implementation of advanced filtering techniques was crucial to achieving the device's exceptional accuracy. Kalman filtering reduces noise and uncertainty in sensor readings, while complementary filtering combines accelerometer and gyroscope data for precise angle estimation. These algorithms work together to reduce measurement errors by up to 40% compared to raw sensor readings.
