HC-SR04 ultrasonic sensor uses sonar to determine distance to an object like bats or dolphins do. It offers excellent non-contact range detection with high accuracy and stable readings in an easy-to-use package. From 2cm to 400 cm or 1" to 13 feet. It operation is not affected by sunlight or black material like Sharp rangefinders are (although acoustically soft materials like cloth can be difficult to detect). It comes complete with ultrasonic transmitter and receiver module.
HC-SR04 distance sensor is commonly used with both microcontroller and microprocessor platforms like Arduino, ARM, PIC, Raspberry Pie etc. The following guide is universally since it has to be followed irrespective of the type of computational device used
Used to avoid and detect obstacles with robots like biped robot, obstacle avoider robot, path finding robot etc.
Used to measure the distance within a wide range of 2cm to 400cm
Can be used to map the objects surrounding the sensor by rotating it
Depth of certain places like wells, pits etc can be measured since the waves can penetrate through water
