    The only complaint is that the sensor can only detect above 2 cm so if your project requires you precise measurements, I recommend you to set an offset of 2 cm. Other than that it's a good and rigid sensor, it's fallen so many times but still it worked at the end.

    the crystal oscillator is not present in sensor and it is hc-sr04p .The product is very well packed but it is different from photo which is given ,it works good but that's not fair to give different product to customer , very bad , don't do this to other customer. Okk.
