HEAD to TOE Product User’s Manual - HC­SR04 Ultrasonic Sensor 1.0 INTRODUCTION The HC­SR04 ultrasonic sensor uses sonar to determine distance to an object like bats or dolphins do. It offers excellent non­contact range detection with high accuracy and stable readings in an easy­to­use 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 es plete with ultrasonic transmitter and receiver module.
