KY-037, High Sensitivity Sound Sensor Module

The KY-037 Sound Sensor Module is a highly sensitive module designed for detecting sound intensity in the environment. It features an electret microphone and an LM393 comparator, providing both digital and analog outputs. The digital output can be triggered when the sound intensity exceeds a set threshold, which can be adjusted with the onboard potentiometer. Its dual output options make it ideal for sound level monitoring, alarms, and interactive sound-responsive applications.

Key Features:

• High-sensitivity microphone for detecting sound levels.
• Adjustable trigger level via onboard potentiometer.
• Dual outputs: analog and digital for flexible interfacing.
• Indicator LED for sound detection status.
• Suitable for voice-activated projects, alarms, and sound sensing.
• Compatible with Arduino, Raspberry Pi, and other microcontrollers.

Additional Specifications:

• Type: Sound Sensor Module
• Input Voltage Range: 3.3-5V
• Output Voltage Range: 0-Vcc,0 Or Vcc
• Current Consumption: <5Ma
