ARENTI LM393 Microphone Sensor 5pcs 280pcs Wires 10cm 20cm

SKU CH-TR4C-46BV7

Five LM393 sound-detection modules with 280 assorted 10 cm and 20 cm jumper wires for breadboard prototyping

  • High-sensitivity sound detection with LM393 electret condenser microphone module
  • Build acoustic control lights or sound-and-light alarms using a photosensitive sensor
  • 280 breadboard jumper wires in 10 cm and 20 cm lengths for flexible prototyping
  • 40-pin male-to-female, male-to-male and female-to-female Dupont cables included
  • Cables separate into custom assemblies to fit non-standard or odd-spaced headers

Sound detection kit

This kit bundles five LM393 electret condenser microphone modules with 280 assorted breadboard jumper wires. It is aimed at hobbyists, students and developers building sound-triggered circuits such as acoustic lighting or alarm prototypes. The components arrive new and ready for breadboard or perfboard assembly.

LM393 comparator threshold

Each module uses an LM393 comparator to convert the microphone signal into a clean digital output when sound exceeds an adjustable threshold. This single specification decides whether the board suits a project that needs a simple on/off trigger rather than a proportional audio waveform.

Five modules and 280 wires

The five modules give enough channels for multi-zone detection or redundant prototypes. The 280 dupont wires in 10 cm and 20 cm lengths — male-to-female, male-to-male and female-to-female — cover typical breadboard layouts, but very large or permanently soldered installations will need additional cabling.

Questions about this item

How does the LM393 module behave once it is wired into a circuit?

The electret condenser microphone detects sound and the LM393 comparator outputs a digital high or low level that can drive an acoustic control light or sound-and-light alarm alongside a photosensitive sensor.

What interface does the module use and what does it limit?

The board provides a simple digital output from the LM393 comparator, so the interface caps the signal to an on/off threshold rather than a continuous audio waveform.

What physical connections are needed to mount the five modules and the jumper wires?

Each module has header pins for breadboard insertion, and the 280 dupont cables — 10 cm and 20 cm lengths in male-to-female, male-to-male and female-to-female — can be separated to fit odd-spaced headers.
