Overview of the KY-017 Mercury Switch Module
The KY-017 Mercury Switch Module is a simple yet effective sensor used primarily for detecting tilt and movement. It operates based on a small mercury ball contained within a glass tube, which completes an electrical circuit when the module is tilted.
Key Features
- Functionality: The module detects orientation changes. When tilted, the mercury ball moves to either make or break the circuit, triggering an output signal 1.
- Components: It typically includes a mercury switch, a 680Ω resistor, and an LED that lights up when the tilt is detected 1 2.
- Compatibility: The KY-017 module is compatible with various microcontroller platforms, including Arduino and Raspberry Pi, making it versatile for DIY electronics projects 2.
Technical Specifications
- Input Voltage: The module operates within a voltage range of 3.3V to 5.5V 3.
- Pin Configuration: It has three pins: GND (ground), VCC (power), and SIGNAL (output).
- Size: The module is compact, measuring approximately 18x15mm, which makes it suitable for integration into various projects.
Applications
The KY-017 module is widely used in projects that require tilt detection, such as:
- Robotics: To detect the orientation of robots or vehicles.
- Alarm Systems: For triggering alarms when a device is tilted 4.
- Interactive Displays: To create responsive installations that react to user movements.
This module is an excellent choice for hobbyists and professionals looking to incorporate tilt detection into their electronic projects.
