The units impressed me quite a bit. Packaged and sealed in static bags, each unit was overpacked in one bag, along with all the other units. units, I tested each and found that all of the sensors worked correctly. The settings I use are 4 and 5. The maximum voltage that can be used to sense objects is 10Vdc The width of the picture is 13cm. Two LEDs, one to indicate power and another when an object is sensed, indicate when the units are working. They have an adjustment pot for varying the distance, as well as a pot to adjust the distance. This gave me a better sense of what to do when Specifically, I observed that all the modules appeared to be well designed and extremely well constructed for their.
This is the second time I've purchased these from HiLetGo. My first batch of orders from them were fine, so I bought another batch from them. Both of these have been fine so far.
This set of parts was of very high quality, arrived quickly, and I'm happy with it.
It is a very good product.
In spite of the fact that it is advertised to be able to detect objects to a distance of 30 cm, it did not work beyond 20 Although I tried adjusting the screw in different directions, I was only able to get the sensor to detect up to a maximum distance of *10 cm. When I bought it I knew it would result in a digital output, but it would be nice to have an analog version so you can write code that is dependent on the distance between two points.
Even though it detects a distance of less than 10cm, some have stated that it is even closer. The distance I got to with mine was only about 5cm. The second one even did not You need to locate another set of sensors that have You can avoid headaches by saving time.
The sensors should be of good quality. A little bit better.
