  • 5Pcs Ultrasonic Sensor Module Kit HC-SR04 Distance Sensor with 3pcs Mounting Bracket Compatible with Arduino UNO Mega R3 Mega2560 Duemilanove Nano Rapsberry Pi 3 Robot XBee ZigBee
    Quality -- Power Supply : 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 × T × C ( L is the distance, T is the time between the emission and reception, and C is the sonic speed ) Package Include -- 5 X HC-SR04 Ultrasonic Sensors , 10 X Female-Male Dupont Cables , 10 X Female-Female Dupont Cables
