This module acts as a switch with sound as input. When a sound is detected above the set sensitivity, this module briefly signals. This module can be used as a blow sensor or a trigger when too much noise is made. Properties: * Voltage: 4V - 6V * Adjustable sensitivity * Output: Digital * Output LED (on when output = 1) * Comparator chip: LM393 Interface: * VCC: 4V - 6V * GND: GND * DO: digital output (0 and 1) https://elecena.pl/product/27738340/opencircuit-sound-detection-sensor-module 2025-01-22 https://elecena.pl/product/27738340/opencircuit-sound-detection-sensor-module 2025-03-22 https://elecena.pl/product/27738340/opencircuit-sound-detection-sensor-module 2025-04-20 https://elecena.pl/product/27738340/opencircuit-sound-detection-sensor-module 2025-04-23 https://elecena.pl/product/27738340/opencircuit-sound-detection-sensor-module 2025-04-24 https://elecena.pl/product/27738340/opencircuit-sound-detection-sensor-module 2025-11-06 https://elecena.pl/product/27738340/opencircuit-sound-detection-sensor-module 2026-02-23 https://elecena.pl/product/27738340/opencircuit-sound-detection-sensor-module 2026-02-25 https://elecena.pl/product/27738340/opencircuit-sound-detection-sensor-module 2026-04-14 https://elecena.pl/product/27738340/opencircuit-sound-detection-sensor-module 2026-04-25
