Description
The module with the analog microphone MEMS SPH8878LR5H-1 and the operational amplifier, which allows the direct connection of the system to the ADC converter on the microcontroller. The microphone used is omni-directional, which means that it is good at picking up sound sources from all directions. The microphone port is located on the bottom of the board, so keep this in mind when installing the module in the project. The sensor will allow you to add sound to the application, it will allow you to detect voice, clap or slam the door. Full documentation with examples of use is available on the product page.
