HC-SR04 Ultrasonic Distance Sensor Module – 3.3V/5V Compatible

Give your robot the ability to navigate its environment with the HC-SR04. By emitting ultrasonic sound waves, this sensor calculates the distance to an object with impressive accuracy, just like a bat using sonar. It is the go-to component for obstacle avoidance robots, liquid level monitoring systems, and parking sensors. Unlike older generic models, this “New Version” operates seamlessly on both 3.3V and 5V logic, solving the headache of connecting to modern 3.3V microcontrollers.
