  • 5pcs Ultrasonic Module HC-SR04 MELIFE Distance Sensor with 3pcs Mounting Bracket 2 Wire Set for Arduino UNO Mega R3 MEGA Mega2560 Duemilanove Nano Robot XBee ZigBee
    Parameter -- New Version Power Supply: 3.3V -- 5V DC; Quiescent Current: <2mA; Effectual Angle: <15 degree; Detection Distance: 2cm -- 450 cm; Resolution: 0.3 cm. Operating Principle: Ultrasonic HC-SR04 distance measuring transducer sensor, it consists of ultrasonic transmitter, receiver, and control circuit. HC-SR04 ultrasonic sensor module: Using IO trigger for at least 10us high level signal, when triggered it sends out a series of 40KHz ultrasonic pulses and receives echo from an object, the duration of the signal is the time from sending ultrasonic to returning. Test Distance Formula: The distance between the unit and the object is calculated by measuring the traveling time of sound and output it as the width of a TTL pulse, HC-SR04 test distance following formula -- L = 1/2 x T x C (L is the distance, T is the time between the emission and reception, and C is the sonic speed). Package Include: 5 x New Version HC-SR04 Ultrasonic Sensors, 3 x Mounting Bracket with Screws, 10 x Female-Male Dupont Cables, 10 x Female-Female Dupont Cables.
