Sound Sensors

Omnidirectional MEMS microphone with 24-bit I2S output, ideal for ESP32 audio projects without a separate codec. Provides clear voice and ambient capture, with good signal-to-noise ratio and wide frequency response. Operates at 1.8V-3.3V with low consumption, and left/right channel selection is simply done from the L/R pin.

Omnidirectional MEMS module with I2S output, ideal for audio projects with ESP32 and other microcontrollers, without a separate codec. Delivers 24-bit data for clear capture of voice and ambient sounds, has good signal-to-noise ratio and low power consumption. Operates at 1.8-3.3V , and left/right channel selection is made simply by the L/R pin.

Electret microphone module with MAX4466 amplifier for audio capture and analysis on Arduino and other boards, operates at 2.4-5V with very good results at 3.3V, has direct analog output to ADC, adjustable gain 25x-125x from potentiometer, provides clean signal with good power supply noise rejection, ideal for FFT, voice effects and audio-reactive projects.

Microphone module with increased sensitivity and analog output, ideal for measuring sound levels in Arduino projects and other development boards. Includes integrated amplifier with adjustable gain for adaptation to different audio sources, provides stable signal for AD conversion, operates at 5V and delivers amplitude around VCC/2.

Sound sensor with integrated microphone, ideal for noise-triggered automations such as alarms, lighting or Arduino projects. It detects the presence of sound and provides stable digital output, operates at 3.3–5 VDC, and the sensitivity is quickly adjusted from the potentiometer to adapt to the working environment.

Detects the presence of sound and provides a digital signal for automation and Arduino projects, 5VDC power supply, DO output that switches High or Low when the sound level exceeds the set threshold, adjustable sensitivity from the potentiometer, fast response and easy integration into control and monitoring circuits.

Acoustic control module for simple automation, switches the output with each clap, generates a 5V signal upon detection and returns to LOW upon the second detection, 5VDC power supply, high sensitivity in the 3kHz range for fast response, ideal for use with a 5V relay to control lights or other consumers.
