    The Product description seems more like a review from someone who really bought it. I bought the and was trying to understand why it isn’t working. Read product description now. Didn’t expect negative things mentioned in product description. Such as current consumption, high range and all. My sensor isn’t receiving ECHO signal, now i am guessing it could be due to module need high power while my power adapter is 5V, 1A for (RPI 3 Model B)

    Would appreciate if other owners share their experience.
