<b>[Product Information]</b><br>
<ul>
<li>HC-SR04 Ultrasonic Sensor Distance Module: using IO trigger for at least 10us high level signal</li>
<li>The hc-sr04 arduino 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</li>
<li>Hc-sr04 Test Distance : high level time velocity of sound (340M/S) /2</li>
<li>Hc-sr04 Power Supply : 5V DC; Quiescent Current : <2mA,; Effectual Angle: <15° ; Detection Distance : 2cm~500 cm; Resolution : 0.3 cm</li>
<li>Package Content: 5pcs HC-SR04 in the antistatic resealable bag with a gift</li>
</ul>
