Ultrasonic Sensors Overview from AutomationDirect 

I have to build a project for school. We are designing a sensor that detects people approaching. We will be using a basic breadboard for a prototype so we need one that works with low voltage, what would you recommend?

We purchased one of your UK1A-EP-0E ultrasonic Proximity Switches and it has a +/- 8 degree beam angle. I have proven the concept that it can replace one of the through beam optical sensors we currently have in place for our automated painting process. The issue is that these sensors are used in an array of 16 sensors that are spaced 2" apart over a string conveyor. My concern is the possibility of cross-talk or interference between sensors set at such close proximity. All 16 sensors are set 2" apart, and pointing in the same direction. They are tilted at a 30 degree angle to the plane of the product and the product is irregular, so I suspect the signal reflections might interfere with adjacent sensors. I see some vendors discuss various schemes to counter this issue; some being the synchronizing of multiple sensors and another using an interlocked electronic timing method that sequences the staggered firing of each adjacent sensor. Another manufacturer; (IFM) uses "sound tubes" to help reduce interference and cross-talk. What can you tell me about issues with or methods to compensate for sensor cross-talk or interference? Added: The reason I am wanting to change to Ultrasonic is because our optical through beam sensors typically read through our white plastic parts and the PLC cannot read when to start spraying in automatic. Hence the operator has to run the paint spray guns in manual, which wastes paint, and sometimes they forget, or are slow to set to manual and then we have quality issues. Cross-talk or interference is one of the reasons I haven't really considered diffuse sensors. Thanks,

Hi, I want to know how to adjust the range of an ultrasonic sensor for PLC. They have a default range but how do I modify that range? Is there any other software or al can be done in the same ladder logic software?

Am amazed with the technology of yours... but what will happen if there was a foam above the liquid level.. how will this technology give us the correct reading? can you explain if possible

Hi there, For a project at uni, I need to incorporate a sensor that will sense if someone is walking/moving/standing within a (approximately) 3 meter radius of the product I am designing. If the sensor picks up on the object, a light in the product will fade in. There is no need for the sensor to measure the distance, I just need a sensor that will notice objects within a (+/-) 3 meter radius. The sensor needs to be as small as possible, as there isn't that much space in the housing of the product. It also needs to be as cheap as possible (but still a durable sensor, as the product is designed for a public space (outside)) as it is designed for a municipality. Would you have any recommendations on which sensor to use? I did search the website, but I am not sure on which outputs to use (e.g.). Thank you in advance!

I i wanna see some overview regarding to ultrasonic sensors for robotic hobby (not for industrial purpose). there's such a great difference between these types of approaching.....For example, HC-SR04 is strongly dependent by the type of surfaces, colour, geometry and dimenssions of the target. Much more, it's hardly dependent by the environment conditions, especially by the temperature and light. Neither Ping Parallax ultrasonic sensor isn't so independent of these aspects. I don't say these two sensors aren't able to give good result of the distance measurements, but you need to do a lot of software compensations.....

I saw some videos on youtube in which they use UDS to create a 2D graph of a Room , can that be achieved with a HCSR04 without any special software (matlab) ?

can i use ultrasonic sensor for detecting liquid under high pressure in steel container ? if yes, which type of ultrasonic sensor should i use?

What's a good budget industrial/commercial grade Ultrasonic sensors ranging for 1-2 meters max.how much would they cost.?

Building a Gokart and I want something with proximity detection, what would you recommend?

Hello, Can I apply Ultrasonic Sensors measure the height and wavelength of the water?

If the sensor is fixed along a rope looking down, waiting for a load to come up, would the sensor see the rope even if they are parallel.

I want to check the level of grease in barrel...it possible by ultrasonic sensor?because grease surface is uneven some grease stick at the sides of the barrel..

Please tell what are different types of ultra sonic sensors like thermocuple.

if we use ultrasonic sensor in heavy magnetic field then will it give accurate readings?

Sir , plz send the link of creating 3D model of ultrasonic sensor in autodesk

Is there any contact ultrasonic sensor??

Can ultrasonic sensor differentiate mainly plastic materials?
