hey everyone,
I’m working on a security project where the system activates (e.g., triggers an alarm or lights up an LED) when it detects a loud sound, such as a clap or a door slam. While researching, I came across both electret and condenser microphones, but I’m unsure which one would be better for this application.
Can anyone help me decide which microphone to use?

For a sound-activated security project where you need to detect loud and sudden sounds (e.g., claps or door slams), an Electret Microphone is generally a better choice. Here’s why(see the image attached below.)
Recommendation:
Use an Electret Microphone for your project. It is cost-effective, easy to interface with microcontrollers, and sensitive enough to detect sudden, loud sounds like claps or door slams. You can amplify its output using an op-amp circuit or a microphone module for better performance.
