Measures distances from 0 to 270 cm, with real-time measurements shown on the digital display. LED indicators light up according to the measured range, making distance changes easy to see during operation. A fun STEM gift for teenagers, students, DIY enthusiasts, and electronics lovers.\u003c\/li\u003e\n\u003cli\u003e【Adjustable Distance Alarm】: Set your desired alarm threshold using the two onboard buttons to increase or decrease the detection distance. When an object enters the preset range, the buzzer sounds automatically, providing a hands-on way to explore obstacle detection and distance alarm functions.\u003c\/li\u003e\n\u003cli\u003e【How Ultrasonic Distance Measurement Works】: Learn the basic principle behind ultrasonic ranging. The HC-SR04 sensor sends ultrasonic waves toward an object and detects the reflected waves. The system calculates the distance by measuring the time between transmission and reception, turning an electronics concept into a hands-on experiment.\u003c\/li\u003e\n\u003cli\u003e【STEM Electronics Project】: Clearly labeled component locations and connection points help guide the assembly process. This project provides hands-on practice with electronic components, circuit connections, soldering, and basic distance-sensing technology. Ideal for school STEM projects, home learning, and a creative educational gift for teens and students.\u003c\/li\u003e\n\u003cli\u003e【Paper Installation Manual】: Includes a color-printed English manual with step-by-step instructions, clear illustrations, and detailed assembly guidance. Please note that this soldering project requires basic electronics knowledge, soldering skills, and hands-on ability for assembly.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOverview\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e MiOYOOW\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay Type:\u003c\/strong\u003e digital or led\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e pcb board；resistors and other components\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Items:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Highlight:\u003c\/strong\u003e DIY Distance Measurement Alarm with LED Lights Display, STEM Electronics Project, Soldering Practice Kit for Students Adults\nDIY Distance Measurement Alarm with LED Lights Display, STEM Electronics Project, Soldering Practice Kit for Students Adults\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MiOYOOW","offers":[{"title":"Default Title","offer_id":52555438227676,"sku":"B0DQY22FWC","price":28.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0837\/0913\/3020\/files\/41835dbCJcL.jpg?v=1789998000","url":"https:\/\/stemora.us\/products\/mioyoow-hc-sr04-ultrasonic-distance-sensor-diy-soldering-kit-for-daily-use","provider":"Stemora","version":"1.0","type":"link"}
