HC-SR04 Ultrasonic Sensor

📏 HC-SR04 Ultrasonic Distance Sensor – Precise Non-Contact Measurement
The HC-SR04 Ultrasonic Sensor is a reliable and cost-effective module for distance measurement using ultrasonic waves. It offers precise, non-contact detection, ideal for obstacle avoidance, smart robotics, automation, and distance tracking with Arduino, ESP32, Raspberry Pi, and other microcontrollers.

🔧 Key Features
🌀 Measurement Type: Ultrasonic (non-contact)
📏 Range: 2 cm to 400 cm (0.02 m – 4.0 m)
🎯 Accuracy: ±3 mm
⚡ Operating Voltage: 5V DC
🔌 Interface: 4 Pins (VCC, Trig, Echo, GND)
⏱️ Response Time: <15 ms
💡 Trigger Pulse Width: 10 µs
📦 Compact, easy-to-mount design

📦 Package Includes
• 1x HC-SR04 Ultrasonic Distance Sensor
• Labeled pins: VCC, Trig, Echo, GND
• Ready for Arduino, Raspberry Pi, ESP32, ESP8266, STM32, etc.

🤖 Perfect For
🚗 Obstacle-avoiding robots
🔁 Smart parking systems
📦 Inventory automation
🚪 Motion-triggered doors
📊 DIY distance measurement tools

🛠️ How It Works
1️⃣ Sends ultrasonic pulse via Trig pin
2️⃣ Waits for echo bounce-back
3️⃣ Measures sound travel time
4️⃣ Converts time to distance

💡 Pro Tip: Pair with LCD or buzzer for real-time alerts!
