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 these handy \u003cstrong\u003eHC-SR04 Ultrasonic Sonar Distance Sensors \u003c\/strong\u003eand a pair of flippers. These 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 400cm away, but we think 10cm-250cm will get you the best results.\u003c\/p\u003e\n\u003cp\u003eThese sensors are fast, fairly easy to use, and low cost. They do require powering from 5V for best results: connect GND (ground) and VCC to 5V power. While the \u003cstrong\u003eTrig\u003c\/strong\u003e signal can be 3V or 5V, the 'return' \u003cstrong\u003eEcho\u003c\/strong\u003e signal is 5V logic. For that reason, we include two 10K resistors, use these as a divider to convert the 5V logic level to a safe 2.5V that you can ready with your 3V device.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIf you need a version that also works with 3.3V power and logic, and has a UART output as well as temperature reading, check out the US-100!\u003c\/li\u003e\n\u003cli\u003eIf you want a drop in replacement that works with either 3V or 5V, we have that in stock here.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eYou can use this sensor with Arduino, CircuitPython (for microcontrollers or Raspberry Pi) or MakeCode\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\u003ch2\u003eTechnical Details\u003c\/h2\u003e\n\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e\n\u003cul\u003e\n\u003cli\u003ePower \u0026amp; Logic Voltage: DC 5V\u003c\/li\u003e\n\u003cli\u003eCurrent during measurement: 15mA\u003c\/li\u003e\n\u003cli\u003eUltrasonic Frequency: 40 KHz\u003c\/li\u003e\n\u003cli\u003eMeasuring Angle: 15º\u003c\/li\u003e\n\u003cli\u003eTrigger Input Signal: 10uS high pulse\u003c\/li\u003e\n\u003cli\u003eSensor dimensions (excluding header): 45.5 x 20 x 15.5mm\u003c\/li\u003e\n\u003cli\u003eWeight: 8.7g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"The Pi Hut","offers":[{"title":"Default Title","offer_id":53697530429716,"sku":"sgx1787257918064","price":1.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0946\/9486\/7220\/files\/hc-sr04-ultrasonic-sonar-distance-sensor-2-x-10k-resistors_1.jpg?v=1787257922","url":"https:\/\/regalwearstore.shop\/products\/hc-sr04-ultrasonic-sonar-distance-sensor-2-x-10k-resistors","provider":"My Store","version":"1.0","type":"link"}
