HC-SR04 Ultrasonic Sensor is the HC-SR04 ultrasonic distance sensor and also called as Ultrasonic Range Finder. This is economical sensor provides 2cm to 400cm of non-contact measurement functionality with a ranging accuracy that can reach up to 3mm. Each HC-SR04 module includes an ultrasonic transmitter, a receiver and a control circuit. There are only four pins that you need to worry about on the HC-SR04: VCC (Power), Trig (Trigger), Echo (Receive), and GND (Ground). You will find this sensor very easy to set up and use for your next range-finding project! This sensor has additional control circuitry that can prevent inconsistent “bouncy” data depending on the application. Features: Operating Voltage: 5V DC Operating Current: 15mA Measure Angle: 15° Ranging Distance: 2cm – 4m Package Includes: 1 x HC-SR04-Ultrasonic Range Finder
