  • KY038 is a highly sensitive sound detection module with Analog as well as digital output. This is an arduino compatible module. Using this module you can even measure the intensity of ambient sound. Most of the digital sound sensor module just provides digital output i.e. if sound is present or not. But this Sound sensor module also provides and analog output voltage which is directly proportional to the intensity of the ambient sound.
