Main Description

Sound Detection Module Sensor for Intelligent Vehicle Compatible With Arduino is a Single channel signal output Sensor. The output is effective to the low-level sound signal with good fidelity, When there is sound, outputs low level and signal light.

Key Features:

• Dual Output Mode: Digital output for simple ‘noise/no-noise’ triggers and Analog output for precise sound intensity measurement.

• On-board Potentiometer: Easily adjust the sensitivity threshold for the digital output.

• Stable Comparator: Features the LM393 chip for clean signal processing and low noise interference.

• Visual Feedback: Built-in LEDs indicate power status and digital output activation.”

Technical Specifications

• Operating Voltage: 3.3V to 5V DC.

• Interface: 4-pin (VCC, GND, DO, AO).

• Signal Type: TTL Digital (0/1) and Analog (Voltage).

• Sensitivity: Adjustable via multi-turn potentiometer.

• Microphone Type: High-sensitivity electret condenser microphone.

• Operating Temperature: -20°C to +85°C.

• PCB Dimensions: 32mm x 17mm.
