This repository contains the source code and documentation for creating a simple sound alarm system using a sound sensor, Arduino, a speaker with an SD card module, an SD card, and jumper cables. This ...

Used to detect the intensity of the ambient sound. Output: digital signal (LOW / HIGH). The triggered threshold is adjustable via a built-in potentiometer. Sound Sensor for Arduino, ESP32, ESP8266, ...

I have already made some devices using SeeedStudio’s Seeeduino Nano microcontroller boards and Grove Sensors. In this post I am going to show you how to make a simple sound activated electronic switch ...

The KY-038 sound sensor pinout has 4 pins: VCC, GND, Digital Out, and Analog Out. We can either use the AO pin as an output for analog reading or the DO pin as an output for digital readout. The Sound ...

The Arduino Mega interfaces with a microphone sound sensor module to detect sound levels and frequencies, ideal for audio monitoring, sound-activated systems, and noise measurement applications in ...

In our daily lives, we use thermometers on various occasions and for various purposes, from medical needs to repair and diagnostic purposes. As you know there are different types of thermometers, and ...
