KY-037 Microphone LM393 Sound Detection Module

The KY-037 Voice Recognition Sensor is a sound detection module that can be used to recognize sound and vibration.

• It includes a highly sensitive microphone and an LM393 comparator to provide both analog and digital outputs.
• The analog output (AO) provides a real-time voltage signal corresponding to the detected sound intensity, while the digital output (DO) gives a high or low signal when the sound intensity exceeds a predefined threshold.
• This module is useful for various applications, such as voice-activated projects, noise level monitoring, and sound-activated lighting systems.
• Note: Product may be differ from the picture shown here.
• Operating Voltage: 3.3V to 5V Output: Analog (AO), Digital (DO) Comparator IC: LM393 Package Includes: 1 x KY-037 Microphone LM393 Sound Detection Module.
