Gravity: Digital Shake Sensor
The digital shake sensor detects unidirectional hand movements, preventing false triggers with strong anti-shock capability. It’s compatible with 3.3V/5V controllers.
The digital shake sensor is to detect hand shaking which is only sensitive to unidirectional hand movements. The spring-type vibration switch is used to output a low-level pulse when the user shakes once in the specified direction and the on-board indicator flashes at the same time. Thanks to the unidirectional sensitivity of the vibration switch and the corresponding filter circuit, it has strong anti-shock interference capability to prevent false triggering. Simple and easy, switch controls are all in just a single shake.
