## Description

&amp;nbsp; This is the HC-SR04 ultrasonic distance sensor, now in Red! This economical sensor offers non-contact measurement functionality ranging from 2cm to 400cm, with a ranging accuracy of up to 3mm. Each HC-SR04 module includes an ultrasonic transmitter, a receiver and a control circuit. There are only four pins that you need to worry about on the HC-SR04: VCC (Power), Trig (Trigger), Echo (Receive), and GND (Ground). You will find this sensor very easy to set up and use for your next range-finding project! This sensor has additional control circuitry that can prevent inconsistent &quot;bouncy&quot; data depending on the application. Note: This is the same ultrasonic sensor used with the XRP &amp;amp; XRP DIY kits. &amp;nbsp; Features &amp;amp; Specs &amp;nbsp; Working Voltage (DC): 3.3V~5V Working Current: 15mA Working Frequency: 40Hz Max Range: 4m Min Range: 2cm Measuring Angle: 15° Dimension: 45 x 20 x 15mm &amp;nbsp; Documentation &amp;nbsp; Datasheet
