Unit MIC Microphone Unit Sound Sensor Omnidirectional Electret Microphone MAX4466

Microphone Unit is a sound sensor with a built-in omni-directional electret microphone.<br> The signal is amplified and output by microphone preamplifier max4466. The amplifier can effectively suppress power supply noise and common mode noise, and the output signal has high sound recovery and can be used in noisy environments.<br> The unit can not only output analog signals, but also output digital level signals. The built-in LM393 double voltage comparator can set the comparison voltage threshold by adjusting 10K adjustable resistance.<br> The sensor is very suitable for acoustic electrical conversion, audio recording / sampling, FFT acoustic feedback, voice switch and other projects..<br> Product Features<br> Audio record/sample<br> Built-in microphone preamplifier MAX4466<br> Omnidirectional, 52dB sensitivity<br> Digital output and analog signal<br> Built-in dual independent precision voltage comparator and adjustable resistor, threshold adjustable<br> Development platform: Arduino, UIFlow (Blocky, Python)<br> HY2.0-4P interface<br> Two Lego-compatible holes<br> Applications<br> FFT Spectrum Display<br> Audio Sample / Record<br> Voice Switch<br> Color: White<br> Material: plastic<br> Package Contents:<br> 1x Microphone Unit<br> 1x Grove Cable<br> Only the above package content, other products are not included.<br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
