HC-SR04 Ultrasonic Distance Sensor Arduino Nano 56MHz RFID IC Key TagThis is the HC SR04 ultrasonic distance sensor. This 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
