AOICRIE 5pcs HC-SR04 Ultrasonic Sensor Distance Module for Nano Robot XBee ZigBee by ElecRight for Ultrasonic Proximity Sensors Motion Detectors (5PCS)
ℹ
Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•Test mode :HC-SR04 ultrasonic sensor can send eight 40 kHz and detect whether there is any pulse signal back.If it back, a high level signal will be outputed by IO, and the duration of the signal is the time from sending ultrasonic to returning.
•HC-SR04 Ultrasonic Sensor Distance Module: using IO trigger for at least 10us high level signal.
•Power supply: 5V DC; Quiescent current: less than 2mA, Test distance = ((Duration of high level)*(Sonic :340m/s))/2.
•HC-SR04 Power Supply : 5V DC; Quiescent Current : <2mA,; Effectual Angle: <15° ; Detection Distance : 2cm~500 cm; Resolution : 0.3 cm
•The detection zone: 0.78~196 in/ (2cm~500cm); High precision: up to 0.12 in/(0.3 cm) Effectual angle: less than 15°
