Using your echo-location abilities to detect tasty fish treats. Until genetic modifications catches up with our desires, we'll just have to make do with this handy \u003cstrong\u003eUS-100 Ultrasonic Sonar Distance Sensor \u003c\/strong\u003eand a pair of flippers. The US-100 is very similar to the popular HC-SR04 ultrasonic sensors, and even looks the same, but has a few extra tricks\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eThis sensor can run from 3-5V so you don't need any logic level shifters or dividers. Just power from whatever your microcontroller provides\u003c\/li\u003e\n\u003cli\u003eYou can use in \"HC-SR04\" mode \u003cem\u003eor\u003c\/em\u003e in \"Serial UART\" mode.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eWhen the jumper on the back is removed, it acts like an HC-SR04 with a trigger and echo pin. When the jumper is in place, you use 9600 baud UART to communicate with the sensor. In UART mode, send 0x55 and read back two bytes (16 bit value) that is mm distance, or 0x50 to read the temperature in degrees C. Handy if you want to use with a computer and a USB-serial converter, or some other device that can't do the special timing needed for the HC-SR04 trigger\/echo.\u003c\/p\u003e\u003cp\u003eThese ubiquitous sensors are really common in robotics projects, but they can also be used for automation, interactive art and motion sensing. They work at about 2cm to 450cm away, but we think 10cm-250cm will get you the best results.\u003c\/p\u003e\u003cp\u003eIn HC-SR04 mode (no jumper), you can use this sensor with Arduino, CircuitPython (for microcontrollers or Raspberry Pi) or MakeCode\u003c\/p\u003e\u003cp\u003eIn UART mode (jumper placed), you can use this sensor with Arduino or CircuitPython\u003c\/p\u003e\u003cp\u003eWe carry a large variety of distance sensors here if this fellow isn't what you're looking for.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e \u003cul\u003e\n\u003cli\u003ePower \u0026amp; Logic Voltage: DC 2.4V~5.5V\u003c\/li\u003e\n\u003cli\u003eCurrent: 2mA\u003c\/li\u003e\n\u003cli\u003eOperating Temperature: -20~ + 70º\u003c\/li\u003e\n\u003cli\u003eMeasuring Angle: Less than 15º\u003c\/li\u003e\n\u003cli\u003eDetection Distance: 2cm – 450 cm\u003c\/li\u003e\n\u003cli\u003eAccuracy: 0.3cm +1%\u003c\/li\u003e\n\u003cli\u003eSensor dimensions (excluding header): 45 x 20mm\u003c\/li\u003e\n\u003cli\u003eWeight: 9g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul id=\"product-files\"\u003e \u003c\/ul\u003e \u003c\/div\u003e","brand":"The Pi Hut","offers":[{"title":"Default Title","offer_id":53697531216148,"sku":"tma1787257926936","price":4.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0946\/9486\/7220\/files\/us-100-ultrasonic-distance-sensor---3v-or-5v-logic_1.jpg?v=1787257931","url":"https:\/\/regalwearstore.shop\/products\/us-100-ultrasonic-distance-sensor-3v-or-5v-logic","provider":"My Store","version":"1.0","type":"link"}
