The Grove - Sound Sensor from Seeed Studio uses the combination of a simple electret microphone and a power amplifier to measure ambient sound levels. The sensor outputs an analogue value which is compatible with any microcontroller with a spare ADC input and matching supply voltage. * Operating voltage range: 4 to 12V DC * Operating current (Vcc = 5V DC): 4 to 8mA * Voltage Gain (VS = 6V, f = 1 kHz): 26dB * Microphone sensitivity (1kHz): 52 to 48dB * Microphone Frequency: 16 to 20kHz * Microphone S/N ratio: 54dB Seeed provide technical documentation, example projects and software libraries on their product pages. if you require this information please visit this product's page. https://elecena.pl/product/27185563/seeed-101020023-grove-sound-sensor-based-on-lm386-4v-12v-input 2024-11-08 https://elecena.pl/product/27185563/seeed-101020023-grove-sound-sensor-based-on-lm386-4v-12v-input 2025-03-19 https://elecena.pl/product/27185563/seeed-101020023-grove-sound-sensor-based-on-lm386-4v-12v-input 2025-06-23 https://elecena.pl/product/27185563/seeed-101020023-grove-sound-sensor-based-on-lm386-4v-12v-input 2025-08-02 https://elecena.pl/product/27185563/seeed-101020023-grove-sound-sensor-based-on-lm386-4v-12v-input 2025-08-22 https://elecena.pl/product/27185563/seeed-101020023-grove-sound-sensor-based-on-lm386-4v-12v-input 2026-04-03 https://elecena.pl/product/27185563/seeed-101020023-grove-sound-sensor-based-on-lm386-4v-12v-input 2026-04-27 https://elecena.pl/product/27185563/seeed-101020023-grove-sound-sensor-based-on-lm386-4v-12v-input 2026-05-18 https://elecena.pl/product/27185563/seeed-101020023-grove-sound-sensor-based-on-lm386-4v-12v-input 2026-06-10 https://elecena.pl/product/27185563/seeed-101020023-grove-sound-sensor-based-on-lm386-4v-12v-input 2026-07-03 https://elecena.pl/product/27185563/seeed-101020023-grove-sound-sensor-based-on-lm386-4v-12v-input 2026-07-26 https://elecena.pl/product/27185563/seeed-101020023-grove-sound-sensor-based-on-lm386-4v-12v-input 2026-09-12
