HC-SR04 Ultrasonic Sensor – Arduino Compatible

The HC-SR04 Ultrasonic Sensor is a powerful and cost-effective module for non-contact distance measurement. It provides an accurate range from 2cm to 400cm (1” to 13ft) with a precision of ±3mm, making it ideal for robotics, automation, and object detection applications.

This sensor operates on the principle of sonar, similar to how bats and dolphins navigate. It emits ultrasonic pulses and measures the time it takes for the sound waves to reflect back from an object, determining the exact distance.

Key Features:
✔ Wide Measurement Range: 2cm – 400cm (1” – 13ft)
✔ High Accuracy: ±3mm precision
✔ Power Supply: 5V DC
✔ Low Power Consumption: Quiescent Current <2mA, Working Current 15mA
✔ Fast Response Time: 10µs trigger pulse
✔ Effectual Detection Angle: <15°
✔ Wide Measuring Angle: 30°
✔ Compact Design: 45mm x 20mm x 15mm

How It Works:
1️⃣ Trigger the Sensor: Send a 10µs high-level signal to the trigger pin.
2️⃣ Ultrasonic Burst: The module sends out eight 40kHz pulses.
3️⃣ Echo Reception: The signal bounces off an object and is detected by the receiver.
4️⃣ Distance Calculation: The time taken for the echo to return determines the distance.

Compatibility:
✅ Works with Arduino UNO, Mega, Microchip PIC, STM32, Raspberry Pi, and other microcontrollers.
✅ Suitable for robotics, automation systems, obstacle detection, and smart security applications.

Package Includes:
1x HC-SR04 Ultrasonic Sensor Module
