The HC-SR04 ultrasonic sensor uses sonar to determine distance to an object like bats or dolphins do. It offers excellent range accuracy and stable readings in an easy-to-use package. 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).Ultrasonic Ranging Module HC-SR04 provides..

This Waterproof Ultrasonic Distance Sensor is an industrial grade sensor to measure distance. Interfacing with it is same as another cheap ultrasonic sensor, but it offers better performance and can be used in harsher environments and is waterproof too! It can be easily interfaced with Arduino and Sample codes and projects are available.There are many ultrasonic distance sensors in the m..
