SPH0645 I2S MEMS Microphone Module

SPH0645 I2S MEMS Microphone Module

Sound Detector 20Hz / 10kHz Digital IIS DC 1.62V / 3.6V Omnidirection Multi Directional -26dB Sensor Raspberry Pi

     A very small I2S mems microphone module. It is similar to classic electret microphones. When a sound signal is detected, it is detected and the data is transferred digitally. They have much thinner and smaller structures compared to electret microphones. It is used in cases where analog data cannot be processed. However, the microcontroller that will process the data needs to be more advanced.

     It has filters that will block noise. The microphone can only give the right or left sound. If there is a need for stereo sound, you need to use 2 sensors. The sensor input pin is on the back of the module.  The sensor can operate in the 1.6-3.6V supply voltage range.
