{"title":"HC-SR04-33 Ultrasonic Distance Sensor - 3.3V/5V","handle":"ultrasonic-distance-sensor-3-3v-hc-sr04","url":"/products/ultrasonic-distance-sensor-3-3v-hc-sr04","description":"This economical ultrasonic module provides non-contact distance measurement for range-finding and obstacle-detection projects. It measures from 2cm to 400cm, with ranging accuracy that can reach up to 3mm.Each module includes an ultrasonic transmitter, a receiver and a control circuit. The interface is simple, with four pins: VCC (Power), Trig (Trigger), Echo (Receive), and GND (Ground).This 3.3V-compatible version can be operated at both 3.3V and 5V, making it easier to use with a wider range of microcontroller boards. It also includes additional control circuitry that can help prevent inconsistent “bouncy” data depending on the application.Features:Non-contact measurement functionality from 2cm to 400cm.Includes an ultrasonic transmitter, a receiver and a control circuit.Four-pin interface: VCC (Power), Trig (Trigger), Echo (Receive), and GND (Ground).Additional control circuitry can prevent inconsistent “bouncy” data depending on the application.Can be operated at both 3.3V and 5V.Same ultrasonic sensor used with the XRP kits Beta & DIY.Specifications:Operating Voltage: 3.3V~5V DCCurrent: 15mAFrequency: 40HzMax Range: 4mMin Range: 2cmMeasuring Angle: 15°Trigger Input Signal: 10uS TTL pulseEcho Output Signal: Input TTL lever signal and the range in proportionDimension: 45 x 20 x 15mmRanging accuracy: Can reach up to 3mmA handy sensor for robotics, simple distance measurement, obstacle detection and maker projects using 3.3V or 5V logic.","vendor":"SparkFun","product_type":"Distance Sensor","in_stock":true,"options":[],"variants":[{"id":15738,"title":"Default Title","sku":"SF-SEN-24049","mpn":"SEN-24049","price":12.8,"on_sale":false,"in_stock":true,"available_quantity":55}]}
