2PCS HC-SR04 Ultrasonic Sensor Module Ultrasonic ranging Module with 2PCS Housing Mounting Bracket + 10P Female to Female and 10P Male to Female Jumper Cable for Arduino
Description: 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. HC-SR04 Ultrasonic Distance Sensor is perfect for all kind of projects that need distance measurements, e.g. avoiding obstacles. HC-SR04 provides 2cm-500cm non-contact measurement function, the ranging hight accuracy can reach to 3mm. Technical Specification: Power Supply :DC 5V Quiescent Current : <2mA Working Current: <5mA Level output: high 5V low 0V Trigger Input Pulse width: 10uS Effectual Angle: <15° Ranging Distance : 2cm - 450 cm Resolution : 0.3 cm Measuring Angle: 30 degree Dimensions: 1.3 x 0.4 x 0.1 inch/3.03 x 1 x 0.25 cm (LWH) HC-SR04 The module works: IO trigger ranging to at least 10us high signal; Module automatically sends eight 40kHz square wave, automatically detect whether a signal return; The signal to return, a high IO output, high duration of Test distance = ((Duration of high level)(Sonic :340m/s))/2. HC- SR04 consists of ultrasonic transmitter, receiver, and control circuit. Connection mode: VCC, trig (control), echo (receiving end), GND ground wire.

Product Features
- 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:2 - 450 cm;High precision:0.3 cm;Effectual Angle: < 15.
- Test mode :Using IO trigger for high level signal.( Not less that 10us),The Module sends eight 40 kHz automatically and detect whether there is a pulse signal back.
- Test distance=((high level duration)*(sound wave: 340m/s))/2.
- Package contain:2PCS HC-SR04 Ultrasonic Sensor + 2PCS Mounting bracket; 10PCS Female to Female jumper Wire; 10PCS Male to Female jumper Wire.
