Treedix 5pcs MIC Sound Sensor Module Microphone Noise Decibel Measurement Kit Microphone Electronic Building Block 3p / 4p Interface

Features· The electronic building block is a module that can be assembled, just like the LEGO building block, which is an electronic product assembled by simple plugging.· Compared with traditional circuit modules assembled with universal boards and various electronic components, electronic building blocks have standardized interfaces, plug and play, which simplifies the trouble of building prototype circuits.· Compatible with mainstream 2.54 pitch interfaces and 4P Grove interfaces.· Using M4 standard fixing holes, compatible with Lego, makeblock and other M4 standard kits.· The microphone electronic building block can be connected to the analog I / O port, and its analog value will change when speaking into the microphone. By reading the analog value to store, it can be made into a recorder.
