This repository explains the design and implementation of kalman filters for distance estimation of ultrasonic sensor. The implementation follows the paper 'Kalman Filter Algorithm Design for HC-SR04 ...

TOF sensor is great, precise and fast, but this Ultrasonic sensor can provide wider detecting angle than TOF sensor and longer distance (3-400cm). With this module we used a STM8 MCU as gateway to ...

[Klaus] wanted some sort of aid for parking his car, and after running across a $4 ultrasonic sensor, decided to build his own speaking distance sensor (.de, Google Translation). Inside [Klaus ...
