S5D9 Microphone - Remove Protective Sticker



The S5D9 IoT Fast Prototyping Kit ships with a clear sticker covering the microphone to protect the microphone from dust. Removing the protective sticker will improve microphone sensitivity.

S5D9 Tip: Remove Sound Sensor Cover

Just found this out at the Learn IoT community NY meetup this past week. When you unpack your S5D9 board, take a close look at the sound sensor. If you see two red bars, that means there’s a small plastic cover on it. It will still detect sound, but if you take it off, it becomes more sensitive. Just use your fingernail, it comes off relatively easily.
