Default value for maximum measurement distance is 4m, since HC-SR04 sensor can't measure reliably beyond that. However, if you are using another sensor or if you you don't care about distances larger ...

Abstract: Nowadays the smart house is necessarily useful part of home comfort. Many people can't imagine their lives without smart devices. A lot of companies provide solutions in this field, for ...

Abstract: As a core robotic and vision problem, camera and range sensor calibration have been researched intensely over the last decades. However, robotic research efforts still often get heavily ...

The analog value from the sensor is converted to distance using either a polynomial fit function up to fifth order or a power fit function. By default, this library is set to use polynomial ...
