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.\nThere 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!\nThis sensor has additional control circuitry that can prevent inconsistent \"bouncy\" data depending on the application.\nNote: This is the same ultrasonic sensor used with the XRP & XRP DIY kits.\n\n\n\n\n\n\n \n\n\n\n\n\n\n\n\n\n\n\nFeatures & Specs\n \n\n\n\n\nWorking Voltage (DC): 3.3V~5V\nWorking Current: 15mA\nWorking Frequency: 40Hz\nMax Range: 4m\nMin Range: 2cm\nMeasuring Angle: 15°\nDimension: 45 x 20 x 15mm\n\n\n\n\n \n\n\n\n\nDocumentation\n \n\nDatasheet\n\n\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":141,"title":"Default Title","sku":"SF-SEN-28798","mpn":"SEN-28798","price":12.0,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":169,"option1":"Default Title"}]}
