The Tilt Switch Sensor Module is a ball tilt switch with a metal ball inside. It is used to detect inclinations of a small angle. Tilt switch module and a digital interface, built-in 13 LED build a simple circuit to produce tilt warning lamp 13 comes with digital interfaces of the LED, the tilt switch sensor interface to access digital 3, when the tilt open Off sensor senses a key signal, LED lights, otherwise off. This Tilt Switch Sensor Module For Arduino simple yet effective tilt switch sensor module houses a metal ball which sits in a tube with electric contacts, as your robot or autonomous vehicle tilts, the ball rolls onto the contacts, a circuit is completed and a signal is sent back to your compatible Arduino control system. Features : This module is Small and Simple to use. Digital switch output (0 & 1) High sensitivity Completes the circuit when the module is tilted LED lights up when tilt switch is activated Package Includes : 1 x Tilt Switch Sensor Module.
