The KY-031 Knock Sensor Module is a small sensor module that detects vibrations and knocks in its surrounding environment. It consists of a piezoelectric sensor that converts mechanical vibrations into electrical signals, which are then amplified and filtered to produce a clean output signal. The module is easy to use and can be connected to a microcontroller or Arduino board using three pins: power, ground, and signal. It provides both digital and analog outputs and can detect a wide range of frequencies. The KY-031 Knock Sensor Module is commonly used in projects that require detecting and responding to physical impacts or movements.
Description
KY-031 Knock Sensor Module is a sensor module designed to detect vibration or knocks in its surrounding environment. It is commonly used in projects that require detecting and responding to physical impacts or movements.
The module consists of a small piezoelectric sensor that converts mechanical vibrations into electrical signals. These signals are then amplified and filtered to produce a clean output signal that can be easily interfaced with a microcontroller or other digital circuits.
The KY-031 Knock Sensor Module can detect a wide range of frequencies from low-level vibrations to high-level impacts. It is also sensitive enough to detect small vibrations, making it useful for applications such as detecting footsteps or detecting when a door is opened or closed.
The module is easy to use and can be connected to a microcontroller or Arduino board using three pins: power, ground, and signal. The output signal is typically a digital signal that indicates whether a knock or vibration has been detected.
Here are the technical specifications for the KY-031 Knock Sensor Module:
- Operating Voltage: 3.3V - 5V DC
- Detection Range: Can detect knocks or vibrations with a frequency between 0.5Hz - 20kHz.
- Sensitivity: The sensitivity of the module can be adjusted using the potentiometer on the module. This allows you to set the threshold level for detection of knocks.
- Output: The module provides both digital and analog outputs. The digital output is a high or low signal indicating whether a knock has been detected. The analog output provides a varying voltage that corresponds to the strength of the knock or vibration.
- Operating Temperature: -20°C to +70°C
- Dimensions: The module measures approximately 32mm x 17mm x 8mm (L x W x H).
- Input Interface: The module can be connected to a microcontroller or other digital circuits using a 3-pin interface: VCC, GND, and Signal.
- Housing: The module is housed in a small plastic enclosure that protects the internal components from external elements.
