{"product_id":"large-ultrasonic-sonar-sensor-with-horn-and-uart-output-discontinued","title":"Large Ultrasonic (Sonar) Sensor with Horn and UART Output [Discontinued]","description":"\u003cp\u003eThis impressive-looking horn is actually an ultrasonic sensor, ready for panel mount use. Inside is a module that uses high-frequency signals to determine the distance to a surface, and the horn helps guide the waveform so it can reach farther without spreading too wide. It's elegant looking and is more durable than the 'raw' ultrasonics we sell a lot of, so it would do well in a garage, robot or installation where you want a durable, dust and weather-resistant design. It has a range of 28 cm to 750 cm with a read resolution of 1mm (precision isn't specified, but its probably about 5-10 mm). As you get to the longer distances, its important to take into account the spread of the cone, which is about 40 degrees. We weren't able to get a reading of 750cm, but we did reach 600 cm (in our small apartment).\u003c\/p\u003e\n\u003cp\u003eThis sensor has UART output, so it can connect to a microcontroller or microcomputer with a TTL serial port. You can also connect it to a computer using a USB-to-serial adapter and read data from the operating system's COM or serial port device.\u003c\/p\u003e\n\u003cp\u003eIt comes with a 2mm pitch connector you can cut off or re-purpose. To use, simply connect the red wire #1 to 3 or 5V, black wire #2 to ground, skip #3 and connect #4 to your serial input pin and read the data in at 9600 baud. A blue LED on the back will blink with each reading. Check out our Arduino and Python example code to get readings in a jiffy!\u003c\/p\u003e\n\u003cp\u003eThis sensor has a 'blind' zone distance of 0 to 28 cm, that means\u003cem\u003e it can't accurately tell when something is less than that distance away\u003c\/em\u003e. it's best used when you know that the object you're sensing is at least 30 cm from the sensor!\u003c\/p\u003e\n\u003cp\u003eWe carry a large variety of distance sensors here if this fellow isn't what you're looking for.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eTechnical Details\u003c\/h2\u003e\n\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e\n\u003cul\u003e\n\u003cli\u003eOperating Voltage: 3.3~5V\u003c\/li\u003e\n\u003cli\u003eAverage Current Draw : ≤ 15mA\u003c\/li\u003e\n\u003cli\u003ePeak Current Draw: ≤ 50mA\u003c\/li\u003e\n\u003cli\u003eBlind Zone Distance: 0 ~ 28cm\u003c\/li\u003e\n\u003cli\u003eDetection Range without bell-mouth cone: 28 ~ 450 cm\u003c\/li\u003e\n\u003cli\u003eSensing Angle without bell-mouth cone: 75º\u003c\/li\u003e\n\u003cli\u003eDetection Range with bell-mouth cone: 28 ~ 750 cm (we were able to test it up to 6 meters)\u003c\/li\u003e\n\u003cli\u003eSensing Angle with bell-mouth cone: 40º\u003c\/li\u003e\n\u003cli\u003ePrecision: ±1cm + 0.5%\u003c\/li\u003e\n\u003cli\u003eOutput: 9600 baud TTL UART\u003c\/li\u003e\n\u003cli\u003eResponse Time: 100ms\u003c\/li\u003e\n\u003cli\u003eProbe Center Frequency: 40KHz ±1.0KHz\u003c\/li\u003e\n\u003cli\u003eOperating Temperature: -15 ~ 60 degrees C at \u0026lt;80% humidity\u003c\/li\u003e\n\u003cli\u003eStorage Temperature: -25 ~ 80 degrees C at \u0026lt;90% humidity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul id=\"product-files\"\u003e\n\u003cli\u003eDatasheet\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":43493249056845,"sku":"tng1787258108666","price":19.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/1182\/8301\/files\/large-ultrasonic-sonar-sensor-with-horn-and-uart-output-discontinued_1.jpg?v=1787258113","url":"https:\/\/www.grandorchard.shop\/products\/large-ultrasonic-sonar-sensor-with-horn-and-uart-output-discontinued","provider":"My Store","version":"1.0","type":"link"}
