Description
The KY-037 Sound Sensor Module is an analog and digital output sensor used to detect sound levels in the surrounding environment. It is ideal for creating sound-activated systems, alarms, or projects that require basic sound detection. This module features a built-in microphone and can detect sound intensity or loudness in the surroundings, providing output to microcontrollers like Arduino for further processing.
Key Features:
- Sound Detection: The module detects sound levels and outputs a signal based on the intensity of the sound in the environment. It can be used for applications such as sound-sensitive switches, alarms, or noise-level monitoring.
- Analog and Digital Output: The KY-037 module provides both analog and digital output:
- Analog Output: Provides a continuous voltage signal corresponding to the sound level, allowing you to measure the intensity of the sound.
- Digital Output: Provides a HIGH or LOW signal (usually HIGH when the sound level exceeds a predefined threshold).
- Built-in Microphone: The module features an onboard microphone that captures sound from the environment, converting it into an electrical signal.
- Sensitivity Adjustment: The sensitivity of the sound detection can be adjusted using a built-in potentiometer, allowing the user to fine-tune the detection range based on their requirements.
- Low Power Consumption: The module consumes minimal power, making it suitable for battery-powered projects.
- Easy to Interface: The module is easy to interface with microcontrollers such as Arduino, Raspberry Pi, and other similar platforms.
Specifications:
- Operating Voltage: 3.3V to 5V DC (typical for Arduino and Raspberry Pi)
- Analog Output Voltage: Typically 0-5V depending on the sound intensity
- Digital Output: HIGH when sound is detected, LOW when no sound is detected (usually above a set threshold)
- Sensitivity Adjustment: Potentiometer for adjusting sound sensitivity
- Microphone Type: Onboard electret microphone
- Size: Approximately 4.4 x 3.5 cm (varies slightly depending on the version)
Applications:
- Sound Detection for Arduino Projects: Ideal for creating sound-activated alarms, switches, or notifications. Can be used in security systems, where a loud noise triggers an event.
- Noise Level Monitoring: Can be used in noise level monitoring systems, such as sound meters, for measuring environmental noise.
- Sound-Activated Projects: Perfect for projects that react to sound, such as a sound-sensitive LED light show, or turning on/off a system based on sound.
- Speech Recognition: While not suitable for complex speech recognition, the KY-037 can be used to detect loud sounds or sharp noises in speech-driven systems.
- Toys and Gadgets: Commonly used in interactive toys or educational kits that require basic sound interaction.
Package Includes:
- 1 x KY-037 Sound Sensor Module
