Product Description:

HC-SR04 Ultrasonic Sonar Sensor একটি জনপ্রিয় distance measuring module যা ultrasonic sound wave ব্যবহার করে কোনো বস্তুর দূরত্ব নির্ণয় করে। Sensorটি 40KHz ultrasonic pulse transmit করে এবং object থেকে প্রতিফলিত echo signal গ্রহণ করে distance calculate করে।

এর 2cm থেকে 400cm measuring range এবং 3mm accuracy থাকার কারণে এটি Robotics, Obstacle Avoidance Robot, Smart Parking System, Water Level Monitoring, Home Automation এবং Arduino-based projects-এ ব্যাপকভাবে ব্যবহৃত হয়। Sensorটি non-contact measurement প্রযুক্তি ব্যবহার করে, ফলে কোনো বস্তুর সাথে শারীরিক সংযোগ ছাড়াই নির্ভুল distance measurement সম্ভব। 

Applications:

• Obstacle Avoidance Robot
• Autonomous Vehicle Projects
• Distance Measurement Systems
• Water Tank Level Monitoring
• Smart Parking Systems
• Security and Detection Systems
• Arduino & IoT Projects
• STEM Education Projects
• Automation and Robotics
