KY-017 Mercury Tilt Switch Sensor Module | Robochacha Pakistan

Makers choose the KY-017 Mercury Tilt Switch Module when they need a simple, high-sensitivity way to detect physical inclination. Specifically, the heart of this module is a glass envelope containing a droplet of liquid mercury. As a result, when the sensor is level, the mercury bridges the contact points to complete the circuit. Furthermore, when you tilt the module, the mercury flows away, breaking the connection. This binary “ON/OFF” signal makes it incredibly easy to program for anti-theft systems or interactive toys.

Additionally, the module includes an onboard LED and a 680Ω resistor. Consequently, you can see the sensor trigger visually without even looking at your Serial Monitor. Because of this, the KY-017 Mercury Tilt Switch Module is a reliable choice for beginners learning about digital inputs and tilt-activated triggers.

Key Features ✨

• High Sensitivity: The liquid mercury reacts to even slight changes in orientation. Specifically, it provides a faster response than many mechanical ball-tilt switches.

• Onboard Status LED: The board features a built-in light that glows when the circuit is closed. Therefore, troubleshooting your wiring becomes much simpler.

• Standard 3-Pin Layout: This KY-017 Mercury Tilt Switch Module uses a standard G-V-S interface. Consequently, it is fully compatible with Arduino, ESP32, and Raspberry Pi.

• Non-Contact Switching: The internal switching happens inside a sealed glass tube. As a result, the contacts are protected from oxidation and dust.

• Compact PCB: In addition, the small footprint allows you to mount the sensor easily in tight spaces like robot arms or window frames.
