This economical sensor provides 2cm to 400cm of non-contact measurement functionality with a ranging accuracy that can reach 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 provide inconsistent \"bouncy\" data depending on the application.","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":5024,"title":"Default Title","sku":"SF-SEN-15569","price":10.31,"on_sale":false,"in_stock":true,"available_quantity":464,"option1":"Default Title"}]}
