5 Pack Sound Sensor Module For Voice Detect And Voice Control Switch With Adjustable Sensitivity 3.3V-5V Operation Ambient Noise Detector For Arduino Raspberry Pi Projects
✔️ 3.3V-5V operation, adjustable sensitivity via blue pot
The 5 pack sound sensor module is a compact ambient noise detector that provides a digital 0/1 output when the sound crosses its adjustable threshold. Ideal for Arduino and Raspberry Pi projects, it lets you build voice-activated switches and simple sound-triggered automation. It supports 3.3V-5V logic and is easy to wire via VCC, GND, and OUT.
✅ Operating voltage 3.3V-5V
✅ Adjustable sensitivity via blue potentiometer
✅ Digital output 0/1 for direct MCU input
✅ Small PCB size 32 mm x 17 mm (1.26 in x 0.67 in) with mounting holes
✅ Pack of 5 modules included
