Description: Octopus Electronic Bricks you can use them build electronics projects just as easy as piling bricks. By using Octopus electronic bricks you may connect Arduino / Freaduino compatible boards easily with various digital analog and I2C / Uart interfaces. These the breadboard-less firm connection are prepared to extensive modules like potentiometers sensors relays servos even buttons just plug and play. Vibration Sensor Brick is a module based on vibration trigger switch. When in the stationary state the indicator LED is OFF. When subjected to external vibration touch to achieve the appropriate vibration force or move away from the speed of the appropriate (partial) effort conductive pin will produce an instant turn-on (ON) state. At that time electrical characteristics have changed. While if the external force disappear electrical characteristics will restore OFF state. Through Arduino board D13 port indicator LED on/ off you can clearly see how the vibration sensor works. This module can be used in vibration testing reporting theft alarm smart car and so on.
