Question
How much does wind affect E4PA Ultrasonic Sensor?
Answer
The Ultrasonic Sensor uses air as the translation medium, so it is easily
affected by wind. Care must be taken when using this Sensor but the E4PA
is the least affected by wind out of all the OMRON Ultrasonic Sensors.
For example, wind produced by a 50-cm industrial fan at the highest level
will hardly change the analog output.
