Microphones and sound detectors

Compact 5V noise and sound sensor with a built-in capacitive microphone and a potentiometer for precise sensitivity adjustment. It has a digital output and dimensions of just 32 mm x 15 mm. The module is ideal for Arduino, ESP8266, or Raspberry Pi.

The sensor works excellently in smart lighting projects controlled by sound, alarm systems that react to noise, and interactive installations. It offers simple integration and reliable detection of sudden sounds-for example, clapping.

A compact 2x3W 5V audio amplifier module operating in class D is an ideal solution for DIY systems and small audio projects. It stands out with 90% efficiency and a wide frequency response from 20 Hz to 20 kHz, delivering clear sound. The module supports speakers with 4-8 Ohm impedance and operates from -40°C to 85°C. Thanks to its small size, it works well in portable speakers and interactive devices based on Arduino, Raspberry Pi, or ESP32.

The omnidirectional INMP441 microphone in MEMS technology delivers clear sound and minimal noise. The module uses a digital I2S 24-bit interface for direct connection to ESP32 and Arduino microcontrollers. It stands out with low current draw of 1.4 mA and supply voltage of 1.8 - 3.3 V.

Compact dimensions make the device ideal for speech recognition systems, voice assistants, and WLED reactive lighting projects. It is a reliable solution for digital audio recorders and smart home installations.

The MAX4466 microphone amplifier with an electret microphone delivers high-quality sound in the 20 Hz - 20 kHz range. The module features smooth gain adjustment from x25 to x125. It is fully compatible with popular platforms such as Arduino, ESP8266, ESP32, and Raspberry Pi.

The product is ideal for sound detection systems, music-reactive lighting, audio recorders, and noise level meters. It ensures a stable output signal and excellent sensitivity in any professional or hobby electronics project.

Compact 2x3W stereo amplifier based on the PAM8403 IC in Class D. The module runs on 5V, offers high 90% efficiency and clear sound from 20Hz - 20KHz with 4-8 Ohm impedance. It includes a built-in potentiometer for precise volume control.

With compact dimensions of 28 x 20 x 15 mm, it is ideal for portable speakers, IoT notification systems, and projects with microcontrollers such as Arduino, ESP32, or Raspberry Pi.
