When Should I Use An Ultrasonic Sensor Versus An Optical Sensor? |
|
Answer» Ultrasonic sensors offer advantages when sensing clear objects, liquid level or highly reflective or metallic surfaces. Ultrasonic sensors also function well in wet environments where as an optical BEAM may refract off the water DROPLETS. However, ultrasonic sensors are susceptible to TEMPERATURE fluctuations or wind. With optical sensors, you can also have a small spot size, fast response and in some instances, you can project a visible spot on a target to HELP with SENSOR alignment.
