KY-031 Knock Sensor Module Tap Sensor Module For Arduino

The KY-031 Knock Sensor Module is a vibration sensor that sends a signal when a knock/tap is detected. KY-031 is a small, easy-to-use module that can use with a variety of microcontrollers, including Arduino, ESP8266, ESP32, Teensy, and Raspberry Pi.

Knock/TAP Sensor Module is a simple and effective way to detect knocks or taps. It is a versatile module that can use in a variety of Projects / applications, such as security systems, monitoring systems, and game controllers.

Knock Sensor Module KY-031 can operate with an input voltage of 3-5V. The default output voltage is HIGH (5V), but it can change to LOW (0V) by connecting the OUT pin to the ground pin.

This module consists of a spring-based sensor, a 10 kΩ resistor and 3 male header pins. The spring emits a high signal when a vibration detect.

The KY-031 Knock Sensor Module works on the principle of a vibration sensor. The module has a spring-based sensor that connect to a 10 kΩ resistor. When the sensor vibrate, the spring touches the metal contact on the resistor, which completes the circuit and sends a HIGH signal to the output pin.

TAP/Knock Sensor Module is a simple sensor that consists of a spring-based sensor, a 10 kΩ resistor, and three male header pins. The spring emits a high signal when a vibration detect.

If you are looking for a simple and effective way to detect knocks or taps, then the KY-031 TAP Sensor Module is a good option. It is a versatile and reliable sensor that can use in a variety of applications.

Working Principles : –

The Tap Sensor Module works on the principle of a vibration sensor. The module has a spring-based sensor that connected to a 10 kΩ resistor. When the sensor vibrated, the spring touches the metal contact on the resistor, which completes the circuit and sends a HIGH signal to the output pin.

The working principle of the KY-031 Tap Sensor Module can be summarized as follows:

• The spring-based sensor is in a resting state when it is not being vibrated.
• When the sensor is vibrated, the spring touches the metal contact on the resistor, which completes the circuit.
• The completion of the circuit sends a HIGH signal to the output pin.
• The HIGH signal remains on as long as the sensor is being vibrated.
• When the sensor no longer vibrate, the spring returns to its resting state and the circuit broke.
• The break in the circuit sends a LOW signal to the output pin.

KY-031 Knock Sensor Module Features : –

The Tap Sensor Module detects the knocks and the taps. It can work like a switch. The sensor sends data momentarily to the board. To keep the LED on, the button state change codes should use. So the sensor will work as a switch.
Here are some of the features of the KY-031 Tap Sensor Module:

• Simple to use: The KY-031 Knock Sensor Module is very easy to use. It only has three pins, and it can connect to any microcontroller that has a digital input pin.
• Versatile: The KY-031 Knock Sensor Module can be used in a variety of applications. It is a good choice for security systems, monitoring systems, and game controllers.
• Reliable: The KY-031 Knock Sensor Module is a reliable sensor. It is made with high-quality components, and it is designed to withstand harsh environments.

KY-031 Knock Sensor Module Specifications : –

This Tap Sensor Module is a switch that will detect hit, it is not as sensitive as the vibration switch (KY-002) so can use in projects that may be moving and an impact needs to detect. This sensor acts like a switch that will “make” when the sensor knocked.

Here are some of the specifications of the Tap Sensor Module:

• Input voltage: 3-5V
• Output voltage: HIGH (5V) by default, can change to LOW (0V) by connecting the OUT pin to the ground pin
• Output type: Digital
• Operating temperature: -10°C to 50°C
• Storage temperature: -20°C to 70°C
• Dimensions: 20mm x 20mm x 6mm

KY-031 Knock Sensor Module Applications : –

Tap Sensor can widely use in security systems, or monitoring. You can easily use it with the Arduino board or any other microcontroller. This module is a spring-based sensor that sends a HIGH signal when a vibration is detected.

Here are some of the applications of the Tap Sensor Module:

• Security systems: The KY-031 TAP/Knock Sensor Module can be used to detect knocks or taps on doors or windows. This can use to trigger an alarm or to send a notification to a security system.
• Monitoring systems: The KY-031 TAP/Knock Sensor Module can use to monitor the status of equipment or machinery. For example, it can use to detect knocks or taps on a machine that indicates that it is malfunctioning.
• Game controllers: The KY-031 TAP/Knock Sensor Module can use to create custom game controllers. For example, it can use to create a controller that allows players to control a game by knocking on a surface.

KY-031 Knock Sensor Module Pin Descriptions : –

The KY-031 TAP Sensor Module is very easy to use. It only has three pins, and it can connect to any microcontroller that has a digital input pin. The KY-031 Knock/TAP Sensor Module has three pins:

• VIN: This pin is the power supply for the module. It should connect to a 3-5V power source.
• GND: This pin is the ground for the module. It should connect to the ground of the microcontroller.
• OUT: This pin is the output signal from the module. It will go HIGH when a knock/tap detect.
