HC-SR04 Ultrasonic Distance Sensor, 2cm-400cm Range

The HC-SR04 Ultrasonic Distance Sensor is an essential tool for non-contact distance measurement. Perfect for robotics, automation, and DIY projects, this sensor accurately detects objects and measures distances between 2cm to 400cm. With an operating voltage of 5V and a low power consumption of 2mA, it's a highly efficient sensor for creating obstacle detection and avoidance systems.

The HC-SR04 module features both an ultrasonic transmitter and receiver. Upon receiving a trigger signal, it emits eight 40kHz ultrasonic waves. These waves travel through the air, bounce back after hitting an object, and are received by the sensor, which then calculates the distance based on the time taken for the waves to return. The TTL PWM echo signal output allows easy integration with microcontrollers like Arduino, with simple coding examples available in the download section.

Ideal for a variety of applications, including distance monitoring, level sensing, and automation, the HC-SR04 Ultrasonic Distance Sensor provides consistent and reliable measurements. The module's measuring angle is about 15 degrees, offering precise detection for narrow spaces or object-focused tasks.

With the HC-SR04 Ultrasonic Distance Sensor, building advanced robotics or creating obstacle avoidance systems is both simple and cost-effective. Integrate it with your next project and take advantage of its accuracy and versatility!
