Description:
The Sound Detection Sensor Module is designed to detect sound waves through their intensity and convert them into electrical signals. The microphone detects sound, and the LM393 operational amplifier processes it. The sound level threshold is adjustable via an onboard potentiometer. When the sound intensity surpasses the set threshold, the output is triggered to a low state, indicating the presence of sound. This module provides a digital output signal, making it compatible with microcontrollers for sound detection in various applications such as alarm systems, environmental monitoring, and automation.
Features:
Adjustable Sensitivity: The onboard potentiometer allows for tuning the sound level threshold.
Digital Output: Provides a digital signal (high or low) based on the detected sound intensity.
Microphone-based Detection: The sensor uses a microphone to detect sound waves.
Compact Design: Small and easy to integrate into various projects.
Low Power Consumption: Operates efficiently with a low current draw.
Product Specifications:
Operating Voltage: 3.3V - 5V
Operating Current (at 5V): 4-8mA
Microphone Sensitivity (1kHz): 52-48dB
Microphone Frequency Range: 16-20kHz
Microphone Impedance: 2.2KΩ
Microphone S/N Ratio: 54dB
Output: Digital switching output (High and Low levels: 0 and 1)
Signal Indication: Outputs a low level and lights up the signal LED when sound is detected.
Application:
Ideal for sound detection applications like security alarms, sound-based automation, and environmental monitoring.
Can be used in systems requiring detection of specific sound thresholds for triggering actions or notifications.
