HC-SR04 Arduino Ultrasonic Distance Sensor

 150

HC SR04 HC-SR04 Ultrasonic Sensor also called HC-SR04 Ultrasonic Range Finder. Ultrasonic Sensor
module HC-SR04 provides 2cm – 400cm non-contact measurement function, the ranging accuracy can
reach to 3mm. The modules include ultrasonic transmitters, receiver, and control circuits.
The ultrasonic sensor uses sonar to determine the 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. Its 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 the Ultrasonic Sensor transmitter and a receiver module. This is easily
interfaceable for many microcontrollers like Arduino UNO r3, Microchip PIC, and ST Microcontrollers.
