WWZMDiB JSN-SR04T Integrated Ultrasonic Distance Measuring Sensor Transducer Module Waterproof

So far, this sensor has been about what I expected. Produces okay results within its operational range, and not hard to get up and running- just don’t expect pin-point accuracy.So far, it appears that the minimum distance it can measure is roughly 7.5 inches- closer than that, and it looks like the echo resolves too fast?Other concern is that the sensor I received appears to have maybe been pushed in on one side? It hasn’t been a show stopper yet, but there is evidence that the detection region is off center.All told, competent sensor as long as you go in aware of the potential limitations.
