Early warning systems for earthquakes are designed to detect tremors and offer local inhabitants a few seconds' notice. Using the Quake-Catcher Network (QCN), which connects low-cost Micro Electro Mechanical Systems (MEMS) accelerometers to an embedded system's volunteer network, this functional module is intended to swiftly detect and describe earthquakes. Large-scale tremors have the capacity to seriously harm property and claim lives. The plan is to locate any Earthly jerks or tremors, sound the alarm, and alert the people. This concept may be shown in real life using a MEMS accelerometer mechanism. The present disclosure outlines a technique for detecting seismic movement using an accelerometer (MEMS). Whether this device is situated above or below the concrete foundation, its sensor (MEMS) will deviate from its intended position in the event of an earthquake. As of right now, this sensor fluctuates the voltage according to the angle deviation. The output voltage fluctuation from the sensor is sent to the Arduino's ADC pin, where it is transformed into digital data. After reading this digital data and comparing it to the predetermined threshold, the controller turns on the speaker to recognise the people around. The data is shown on the LCD simultaneously, and it is interfaced with the Arduino controller.
