Robocraze Sound Sensor Module for boards compatible with Arduino | LM393 Sound Sensor | LM393 Sound Detection Module - (Pack of 1)

I am using this product for overhead water tank level monitoring. Sensor is giving accurate measurements.

Good but output voltage is little low

I am just using the transducer part of this since I already have the chip part. And it works as expected. It's pretty pricy though.

It's good enough for detection, however the analogue level signal is not very reliable. The potentiometer varies the digital output threshold level, however can't be used to change sensitivity for the analogue signal, and is merely used for biasing. Also, since it's a piezoelectric microphone, you need a really loud sound in close proximity for it to detect.Distant or soft sounds aren't picked up.I bought 4 for a project, and needed analogue levels, so this was disappointing.A more sensitive condenser microphone is ideal for applications such as mine.Would have been nice if the product page had proper details.

Possibly nothing wrong with seller, but the very product is not correctly designed. It constantly gives erroneous reading. Not at all a good sensor to measure tank water level. Will add lots of frustrations if you rely on its data.

May be its hard to get an accurate reading on these devices. But the sensors on this device is not straight contributing to even higher error.

It is of good quality and easy to use but it is a little overpriced and shipping was late by 2 days
