KY-037 High Sensitivity Sound Microphone Sensor

The KY-037 High Sensitivity Sound Microphone Sensor is a compact sound detection module designed to detect changes in surrounding sound levels. It uses a sensitive microphone to capture sound and converts the detected audio into an electrical signal that can be processed by a microcontroller such as an Arduino.

The module provides both analog and digital outputs, making it suitable for different types of applications. The analog output provides a signal that varies according to the detected sound level, while the digital output can be adjusted using the onboard potentiometer to trigger when the sound reaches a specific threshold.

Its high sensitivity and simple interface make the KY-037 useful for projects involving sound detection, voice or noise monitoring, clapping detection, and interactive electronic systems.

Key Features:

  • High-sensitivity microphone sensor

  • Detects surrounding sounds and noise

  • Provides analog and digital signal outputs

  • Adjustable sound detection threshold

  • Onboard sensitivity adjustment potentiometer

  • Compact and easy-to-use module

  • Compatible with Arduino and other microcontrollers

  • Suitable for breadboards and electronic prototypes

Common Applications:
The KY-037 can be used for clap-activated devices, sound-activated lights, noise detection, voice-related projects, security systems, interactive electronics, Arduino projects, and other applications requiring sound detection.

FAQ

Will this ship from Manila?

Yes — all stock ships from our Quezon City warehouse. Order before 4 PM weekdays for same-day cutoff via J&T or LBC.

Do you ship nationwide?

Yes. Metro Manila usually arrives next-day; provincial 1–3 working days.

Can I get this on a school PO or class order?

Yes — we accept Purchase Orders from accredited schools and universities. Contact us with your PO details and we'll process it.

Is this compatible with Arduino, ESP32, or Raspberry Pi?

Most parts work with common maker boards — check the description for specific pinout / voltage notes. If you're unsure, send us a message before ordering.

What's your return policy?

7-day inspection window for DOA units. Email proof of issue and we'll ship a replacement or refund. Used / installed parts are not returnable unless faulty.

Do you offer technical support?

Yes — questions land on our forum or via email, weekday or weekend. We've actually wired up most of what we sell.
