XiaoR Geek HC-SR04 Ultrasonic Module Distance Sensor 2pcs kits Jetson nano robot smart phone and infrared remoteFeatures: 1. HC SR04 Ultrasonic Sensor Distance Module: using IO trigger for at least 10us high level signal. 2. The Module automatically sends eight 40 kHz and detect whether there is a pulse signal back. 3. If the signal back,through high level,time of high output IO duration is the time from sending ultrasonic to returning. Test distance = (high level time velocity of sound (340M S) 2. 4. Power Supply: 5V DC; Quiescent Current:<2mA; Effectual
