Gravity Digital Shake Sensor

The Gravity shake sensor from DFRobot detects a shaking movement of the hand in one direction. A spring-type vibration switch with filter circuit then outputs a short LOW pulse, and a blue LED lights up at the same time. Because it is sensitive in one direction only, it hardly triggers falsely on shocks and is a simple alternative to a 3-axis accelerometer.

Note: The connection cable can be converted to male pins with a Dupont cable M-M, so that it also fits an Arduino UNO.

Recommended Accessories:

• Dupont Cables M-M 10cm 20 Pieces

Features:

• Sensitive in one direction, insensitive to shocks and false triggering
• Digital output: HIGH at rest, LOW pulse when shaken
