Product description
Sound sensor for detecting sound and ambient noise in electronic projects. The module includes a microphone and the integrated LM386 audio amplifier. This makes it possible to amplify weak audio signals and analyze sound levels with a microcontroller. Used for example in sound detection, sound-activated systems or simple sound-based control systems. The sensor can provide both analog and digital output signals. The analog output can be used to read the sound level, while the digital output can trigger events when the sound exceeds a certain threshold. The sensitivity can be adjusted to adapt the sensor to different environments and applications. Operates with a supply voltage between 3.3 V and 5.3 V and is compatible with development boards such as Arduino, Raspberry Pi and STM32. Suitable for educational projects, robotics and other embedded systems where detecting or reacting to ambient sound is required. Supplied with connection cable (4x dupont female connectors).
