If you're developing wearable devices, asset trackers, or alarm triggers, power consumption is a top priority. When creating motion-activated devices, many makers' first instinct is to use MEMS accelerometers. However, these chips continue to draw current even in standby mode, and a few months of standby can completely drain the battery.
Is there a way to detect shaking, tapping, or vibration while consuming virtually no standby current? This purely mechanical, ultra-sensitive vibration switch makes it possible.
The device features a gold-plated ball structure inside. When vibration or displacement occurs, the ball bounces, directly outputting a continuous sequence of high and low levels to the microcontroller's I/O port. The sensitivity can be fully adjusted via MCU software without any hardware modifications.
