KY-017 Mercury Tilt Switch Sensor Module – Digital Sensor for Arduino

KY-017 Mercury Tilt Switch Sensor Module for Arduino

Buy the KY-017 Tilt Switch Sensor Module online in Pakistan from Robostan.pk. This compact digital tilt detection module is designed for Arduino, ESP32, Raspberry Pi, robotics, automation, and DIY electronics applications.

The KY-017 Tilt Sensor detects changes in its orientation using an internal conductive tilt switch. When the module is tilted into a position that closes or opens the switch contacts, its digital output changes state, allowing a connected microcontroller to detect the movement.

Common KY-017 modules use a sealed mercury tilt switch, although alternative versions may contain a mechanical ball switch. Confirm the physical construction of your module before use.

How Does the KY-017 Tilt Sensor Work?

The KY-017 uses a conductive switch that responds to its physical orientation.

When the module is positioned so that the switch contacts are connected, a closed electrical circuit is formed. Tilting the board in another direction can separate the contacts and open the circuit.

This switching action changes the digital signal read by a connected microcontroller.

The controller can use these changes to trigger an alarm, activate an indicator, count tilt events, or perform a programmed action.

Important: The KY-017 provides a basic switching indication. It does not measure the precise tilt angle in degrees and is not a gyroscope or accelerometer.

KY-017 Pinout

• S (Signal): Digital tilt detection output
• + (VCC): Positive power supply
• - (GND): Ground connection

Connect the signal pin to a suitable digital input, VCC to the appropriate regulated supply, and GND to controller ground.

Depending on the circuit configuration, the sensor may produce an active-low signal when the switch closes. Always test the switching behavior of your actual module.

Arduino Compatibility

The KY-017 Tilt Switch Module is suitable for Arduino UNO, Arduino Nano, Arduino Mega, and other compatible development boards.

A digital input pin can monitor the sensor signal and identify when the switch changes state.

Arduino code can then control LEDs, buzzers, displays, or other appropriate electronic outputs in response to tilt detection.

ESP32 and Raspberry Pi Compatibility

KY-017 modules can also be integrated into compatible ESP32 and Raspberry Pi projects using a digital GPIO input.

For 3.3V-only controllers, use a suitable 3.3V supply and ensure that the module output does not exceed the controller's permitted input voltage.

KY-017 vs KY-020 Tilt Sensor

The KY-017 and KY-020 are commonly used for simple movement and tilt detection, but they can use different switch constructions.

• KY-017: Commonly sold with a sealed mercury tilt switch or alternative ball-switch construction.
• KY-020: Commonly uses a mechanical ball tilt switch.

Both provide basic orientation-dependent switching signals rather than precise angular measurements.

Why Choose the KY-017?

Simple Digital Interface: Easy to read using a compatible microcontroller GPIO input.

Compact Design: Suitable for small electronics and automation projects.

Contact-Based Detection: Provides a basic ON/OFF response to changes in orientation.

Educational Value: Useful for learning about digital sensors, switches, and microcontroller input processing.

Important Safety and Usage Notes

• Check whether your particular KY-017 uses mercury or a mechanical ball switch.
• If the module contains mercury, do not break, open, crush, or heat the sealed capsule.
• If a mercury-containing capsule is damaged, keep people away and seek appropriate hazardous-material cleanup guidance.
• Do not dispose of mercury-containing sensors in ordinary household waste.
• Follow applicable handling, shipping, and disposal requirements.
• Use only a compatible regulated low-voltage DC supply.
• Verify the actual board's pinout before wiring.
• The sensor does not provide precise inclination measurements.
• Rapid movement may cause contact bouncing; software debouncing may be required.
• Do not connect motors or other high-current loads directly to the output.
• Do not use the module as the sole safety device in critical equipment.
