Description
C-SR04 Ultrasonic Sensor Module – High-Precision Distance Measuring Sensor for Arduino & Robotics (Pack of 2)
Product Description:
The HC-SR04 Ultrasonic Sensor Module is an advanced distance measuring sensor designed for robotics, automation, and security applications. It operates by emitting ultrasonic waves and calculating the time taken for the echo to return, determining the distance to an object.
Equipped with two ultrasonic transducers, this sensor module functions similarly to sonar technology, making it ideal for applications like obstacle detection, parking assistance, liquid level measurement, and robotic navigation.
Key Features:
✔ High Accuracy: Measures distances from 2 cm to 400 cm with 3mm precision.
✔ Wide Applications: Suitable for Arduino, Raspberry Pi, robotics, and IoT projects.
✔ Energy Efficient: Consumes less than 15mA of power.
✔ Compact Design: Easy to integrate into DIY electronics and automation projects.
✔ Fast Response Time: Provides real-time distance measurement with an accuracy of up to 80 cm in practical use.
Specifications:
-
Operating Voltage: +5V
-
Operating Current: <15mA
-
Theoretical Measuring Range: 2 cm to 400 cm
-
Practical Measuring Range: 2 cm to 80 cm

How It Works:
-
The ultrasonic transmitter emits a high-frequency sound wave.
-
The wave bounces off an object and returns to the receiver.
-
The sensor calculates the time delay and determines the distance using the speed of sound.
Applications:
-
Obstacle avoidance in robotic navigation
-
Smart parking assist systems
-
Liquid level measurement for tanks
-
Security systems with motion detection
-
DIY automation and IoT projects
This HC-SR04 Ultrasonic Sensor Module is a must-have for electronics hobbyists, engineers, and students looking to develop intelligent automation systems.
