Earthquake Detector & Alarm using XIAO RP2040 | SekhoHub |
Overview.
Earthquakes are scary natural disasters that can cause a lot of damage and danger. Imagine if there was a way to know when an earthquake might happen a little bit before it does. That would give us time to protect ourselves and our things.
In today’s tutorial, we are going to make an “Earthquake Detector” using the XIAO RP2040 Microcontroller and Vibration Sensor.
What is an earthquake detector?
An earthquake detector is a device designed to sense and detect movements or vibrations in the ground that occur during an earthquake. The detector can use various sensors, such as accelerometers or gyroscopes, to pick up these movements. When it senses unusual ground activity, it triggers an alarm or sends out warnings to alert people in advance about the possibility of an impending earthquake
