KY-017 Mercury Tilt Switch Sensor Module

⚡ KY-017 Mercury Tilt Switch Sensor Module ⚡

The KY-017 module is a tilt and vibration detection sensor that uses a small mercury switch. When the module is tilted or shaken, the liquid mercury completes or breaks the circuit, generating a digital signal readable by microcontrollers such as Arduino or Raspberry Pi. It is widely used for detecting motion, tilt, or vibration in simple electronic projects.
