【Ultrasonic Range Alarm Kit】: After soldering, you'll have a practical ultrasonic distance measurer kit. The real-time measurement is displayed on the digital tube, and corresponding LED lights will light up for a more intuitive data readout. Plus, when the measured distance falls below a set threshold, the electronic kit will emit a warning beep, alerting you instantly.
【Functions & Features】: Measures distances from 0 to 270cm. The first LED light turns on when the distance exceeds 30cm, and all LEDs light up when the distance surpasses 270cm. Customize the obstacle avoidance distance with two simple buttons for quick adjustments (increase or decrease). This DIY soldering kit is not only a great way to learn electronics but also a practical tool for everyday use.
【Operational Principle】: The ultrasonic ranging system is based on the reflection of acoustic waves when encountering obstacles. The HC-SR04 ultrasonic sensor measures the time difference between transmitted and received ultrasonic waves to calculate the distance between the obstacle and the sensor.
【STEM School Learning Kit】: The connection that was clearly mapped and labeled on the board makes it easy to solder. In addition to teaching fundamental mechanical and electronic concepts, this soldering practice kit is beginner-friendly, appealing to all skill levels. Perfect for hands-on projects, STEM learning, and obstacle detection applications!
【Paper Installation Manual】: This solder practice kit includes a color-printed user manual that guides you through the installation process step-by-step with clear graphics and text. It makes soldering straightforward and enjoyable. But please note, this soldering kit requires certain foundation of basic electronic theoretical knowledge and soldering and hands-on ability.
