Features:

1. The HC-SR04 ultrasonic sensor uses sonar to determine the distance to an object, just like bats do.

2. It offers excellent non-contact range detection with high accuracy and stable readings from 2 cm to 400 cm (1 inch to 13 feet) with an accuracy of 3mm, in an easy-to-use package.

3. Its operation is not affected by sunlight or black material like optical rangefinders are (although acoustically soft materials like cloth can be difficult to detect).

4. The HC-SR04 comes complete with an integrated ultrasonic transmitter and receiver.
