What is the best sensor for distance measurement?

The best sensor for distance measurement depends on your application. Laser distance sensors offer the highest accuracy (±1 mm) and are ideal for long-range and industrial use. Ultrasonic sensors are better for short-range, budget-friendly applications, while infrared sensors work well for basic proximity detection.

How accurate are laser sensors for distance measurement?

Laser sensor for distance measurement can achieve sub-millimeter accuracy. For example, Meskernel’s phase-based laser sensors provide up to ±1 mm precision, making them suitable for precision engineering, industrial automation, and robotic positioning.

What’s the difference between ultrasonic, infrared, and laser sensors for measuring distance?

Laser sensors : High precision, long range, fast response. Ultrasonic sensors : Moderate accuracy, short range, low cost. Infrared sensors : Compact and affordable, but limited in range and accuracy. Each sensor for distance measurement has trade-offs in range, environment adaptability, and measurement frequency.

Can I use a laser sensor for outdoor distance measurement?

Yes, many laser sensor for distance measurement are optimized for outdoor environments. For example, the LDL-S model from Meskernel is designed to operate in strong sunlight and achieve reliable readings up to 30 m outdoors with ±1 mm accuracy.

Which distance measurement sensor works best for AGVs or warehouse automation?

For AGVs, forklifts, or robotic arms, you need a sensor for distance measurement that is both accurate and fast. High-frequency laser sensors like the LDL-20-20 Hz offer reliable performance in dynamic, industrial settings with sub-millimeter precision.

What communication interfaces do distance measurement sensors support?
