Ultrasonic Sensor
Ultrasonic sensors are non-contact devices that measure distance, detect objects, or monitor levels using ultrasonic sound waves. By emitting high-frequency sound pulses and measuring the time it takes for the echo to return, these sensors provide accurate measurements of object proximity and positioning.
Ultrasonic Sensor Market Size was valued at USD 05 Billion in 2022. The Ultrasonic Sensor market industry is projected to grow from USD 09 Billion in 2023 to USD 16 Billion by 2030, exhibiting a compound annual growth rate (CAGR) of 13.00% during the forecast period (2023 - 2030).
Ultrasonic sensing technology is widely used in automotive safety systems, industrial automation, robotics, healthcare, and smart consumer devices. Their ability to function in challenging environments—such as dust, darkness, or clear liquids—gives them a distinct advantage over optical or infrared sensors in many applications.
