High sensitivity microphone sensor module

The High sensitivity microphone sensor module is a small board with an electret microphone that picks up sound and turns it into an electrical signal a microcontroller can read. It lets an Arduino, ESP32 or ESP8266 react to claps, voices, knocks and general noise levels, which makes it a common part in sound-activated and noise-monitoring projects for students and makers.

High sensitivity microphone sensor Specifications

• Sensor: electret condenser microphone
• Function: detects sound and changes in noise level
• Connection: header pins for Dupont jumper wires
• Works with: Arduino, ESP32, ESP8266 and other microcontroller boards

High sensitivity microphone sensor Applications

• Clap switches and sound-activated lights
• Noise level monitoring in rooms, workshops and classrooms
• Robots that start, stop or turn when they hear a sound
• Knock and tap detection projects
• STEM classes and sensor experiments

What's in the Box

• 1 × microphone sensor module

Tip: Check the pin labels printed on the board before wiring, and if the board supports 3.3 V, power it from 3.3 V when you use it with an ESP32 so its output stays at a safe level for the input pin. A module like this measures how loud a sound is; it is not meant for recording audio or recognising speech.
