In stock
The high sensitivity sound detection module is an analog/digital sensor with a condenser microphone for detecting changes in environmental noise. Commonly used to detect sound levels above a set threshold, adjustable via the onboard potentiometer.
The digital output provides a HIGH signal when sound exceeds the threshold, while the analog output gives noise level values, influenced by voltage and potentiometer settings, without reconstructing audio. Compatible with Arduino, ESP32, ESP8266, and Raspberry Pi, this module is ideal for sound detection projects.
- Operating Voltage: 3.3V to 5V DC.
- LM393 comparator with threshold preset.
- PCB Size: 3.4cm * 1.6cm.
- Induction distance: 0.5 Meter.
- Operating current: 4~5 mA.
- Microphone Sensitivity (1kHz): 52 to 48 dB.
- Easy to use with Microcontrollers or even with normal Digital/Analog IC.
- Small, cheap and easily available.
