HC-SR04 Ultrasonic Sensor：This is a device that can use sound waves to measure the distance of an object. It measures distance by emitting a sound wave of a specific frequency and listening to the bounce of that sound wave. The distance between the sonar sensor and the object can be calculated by recording the time elapsed between the generation of the sound wave and the bounce of the sound wave Working Voltage: 5V DC；Quiescent current: less than 2mA Ranging Distance：2cm - 450 cm；High precision: 0.3 cm Effectual Angle: <15°

It also provides NO (Normally Open) / NC (Normally Closed) interface. Standardized shield form factor enables smooth connection with Arduino and compatibles. The shield also has four LED indicators to show the on/off state of each relay.Relays are useful in switching on/off AC appliances like fan, light, motor or high current DC actuators like solenoid valve etc.
