The MAX9814 Microphone Amplifier Module with Auto-Gain Control is a versatile audio sensor designed for Arduino and other microcontroller projects. This module features a high-performance electret microphone and an integrated amplifier with automatic gain control (AGC), which ensures consistent audio signal levels regardless of the input volume. It’s ideal for applications involving sound detection, voice activation, and audio signal processing.

Features:

• Auto-Gain Control (AGC): Automatically adjusts the gain to maintain a stable output level, accommodating varying sound intensities.
• High-Quality Microphone: Equipped with a sensitive electret microphone for clear and accurate sound capture.
• Adjustable Gain: Includes a potentiometer for manual adjustment of the gain if needed.
• Easy Integration: Outputs an analog signal that can be directly read by Arduino analog input pins.
• Wide Operating Voltage: Supports a range of 2.7V to 5.5V, making it compatible with various power sources.
• Compact Design: Small and lightweight, suitable for incorporation into diverse projects and prototypes.
