Introduction
This tilt switch is a digital module based on the steel ball switch. The ball inside the module will roll to the lower side under gravity to have the switch connected or disconnected. You can also use it just as a tilt sensor. It supports digital output and has higher security than mercury switches. And the module can be used with maincontrollers such as micro:bit and Arduino, suitable for not only Mind+ and makecode graphical programming but also non-programming projects.
Specification

Pinout
| NO. | Label | Description |
|---|---|---|
| 1 | GND | Power - |
| 2 | VCC | Power + |

Usage Description
The sensor can be used with Arduino and micro:bit Sensor Expansion Shield to make amazing interactive projects. And it has higher security than mercury switches.
The switch can be turned on or off by controlling the its tilt.
When it is placed horizontally, it outputs low; when it tilts, output high.
Working Principle
This tilt switch is a digital module based on the internal steel ball. When the switch tilts by external force, the ball will roll to the lower side under gravity and the normally-closed contact will disconnect; when it returns to keep horizontal, the ball will roll to the initial position and the contact will connect again. Also, you can use it just as a tilt sensor.
Application
1. Tilt Alarm System
Description:
When the tilt sensor detected tilt, the buzzer module will be activated and start to buzz to give an alarm.
