Sound Detection Sensor Module
A sound sensor is a component designed to perceive sound waves by gauging their intensity and transforming them into electrical signals.
The sound detection sensor module tailored for Arduino is engineered to identify if sound surpasses a predefined threshold. It utilizes a microphone to pick up sound, which is then processed through an LM393 operational amplifier. The threshold for sound levels is adjustable through a built-in potentiometer. Once the sound level surpasses the set threshold, an LED on the module illuminates, and the output signal is lowered.
Features:
- Operating voltage 3.3V-5V
- Outputs digital switching output (high and low levels 0 and 1
- Operating current (Vcc=5V): 4-8mA
- Microphone sensitivity (1Khz): 52-48dB.
- Microphone Impedance: 2.2KΩ
- Microphone Frequency: 16-20Khz.
- Microphone S/N ratio: 54dB.
- Signal output indication.
- Single-channel signal output
- Outputs low level and the signal light when there is sound.
