Ultrasonic Sensor

A ultrasonic sensor is an intelligent device that can measure the distance between a target and itself by sending out a sound wave and receiving the echo from the object. Just like how bats traverse through the dark, these sensors can “see” (range distance to) objects without requiring light as illumination – so they are a great low-light or even no-light sensor. They work just as well in light and sound.

Ultrasonic sensors are some of the most reliable sensors for distance measurement in electronic and robotic areas nowadays. Devices such as HC-SR04 Ultrasonic Sensor Distance Measuring Module HW-626 and HY-SRF05 Five Pin Ultrasonic Ranging Module are commonly used for educational and hobby robotics. They read accurately and are easy to interface with a microcontroller like Arduino or Raspberry Pi.

The Waterproof Ultrasonic Obstacle Sensor and Reversing Radar Sensor with Separate Probe are ideal for industrial or outdoor use as they provide reliable performance in heavy-duty environments. They are used a lot in parking systems, liquid level detection, and automation lines where accuracy and long life are very important.

The US-100 Ultrasonic Sensor with temperature compensation automatically adjusts for changes in the environment, and the Digital Display Control Board for HC-SR04 shows measurements right away. The TCT40-16R Ultrasonic Transducer Pair is perfect for engineers who want to make their own distance-sensing systems.

Our selection of ultrasonic sensors has the right mix of dependability, performance, and value for every project, whether you're a hobbyist, a student, or an industrial designer.
