SOUND SENSOR MODULE BLUE
Rs. 47.60
Sound detection sensor module (blue PCB) for Arduino. Detects sound intensity via microphone fed into an LM393 op-amp. Adjustable sensitivity potentiometer sets the threshold — output goes low and LED illuminates when sound exceeds the set level. Single-channel digital output compatible with 3.3–5V systems.
