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
