Ultrasonic Sensor for Distance Measurement, 100-1000mm

An ultrasonic sensor for distance measurement is a device that uses ultrasonic sound waves (typically above 20 kHz) to measure the distance between the sensor and an object. It works by emitting a sound pulse, measuring the time it takes for the pulse to reflect back from the object, and calculating the distance based on this time.

Ultrasonic sensors are an affordable and reliable choice for distance measurement. Unlike laser sensors, they are less affected by dust, fog, or other environmental factors, making them ideal for outdoor and industrial use. They also provide non-contact distance measurement, ensuring safety when measuring delicate objects. Additionally, ultrasonic sensors are easy to integrate with microcontrollers and consume low power, making them a versatile option for various applications requiring distance detection.

Ultrasonic sensors are most effective for measuring distance to solid objects with a hard surface. Soft or absorbent materials (like foam or fabric) or transparent materials (like glass) may not reflect sound waves efficiently, leading to inaccurate distance readings. The sensor works best with surfaces that are hard and relatively smooth.
