The 7Semi Electret Mic Breakout Board is a compact solution that amplifies sound signals picked up by an electret microphone (100Hz to 10kHz). With a 60x mic preamplifier, it is designed to detect voice, claps, door knocks, or any other sounds that are loud enough for a microcontroller's ADC. The fully assembled breakout board works with voltage ranging from 2.7V to 5.5V.
The Electret Microphone Breakout transforms the sound's amplitude into electrical signals through capturing sound waves that occur between two conductive plates in the microphone. These electrical signals are amplified and read by the microcontroller's analog-to-digital converter.
An Electret Microphone Breakout is a small circuit board that provides an easy way to connect an electret microphone to a microcontroller or other electronic device. The electret microphone is a type of microphone that uses a permanently charged material to capture sound waves and convert them into electrical signals. The Electret Microphone Breakout typically includes a preamplifier circuit that amplifies the signal from the microphone and allows it to be easily processed by a microcontroller. This breakout board is commonly used in applications such as voice recognition systems, sound activated switches, and audio recording devices. The Electret Microphone Breakout is a simple and cost-effective solution for adding sound capture capabilities to a wide range of electronic projects.
Sound Sensor: A sound sensor is a device that detects and measures sound waves in the surrounding environment. It typically works by converting sound waves into electrical signals that can be processed by a computer or other electronic device. Sound sensors can be used in a variety of applications, such as monitoring noise levels in a factory or detecting the presence of people or animals in a room. They are also commonly used in electronic musical instruments and sound recording equipment to capture and reproduce sound accurately. Sound sensors come in various types, including condenser, dynamic, and piezoelectric, each with its unique characteristics and suitability for different applications.
