DIY Working Model Science Project Circuit Diagram Friends in this video I will show you How To Make An Earthquake Alarm..Earthquake Detector Circuit..Simple Science Project..Friends it is a very simple scien

The construction of the project "Earthquake Detector using Arduino" is so simple, that it looks like the assembling of a few common electronics components. The fact that the project "Earthquake Detector using Arduino" uses Arduino Uno, which is itself a complete circuit, makes this project easier to implement. The Arduino board and

Earthquake Detector Alarm using Arduino and Accelerometer Circuit Diagram
Here is the circuit diagram that represents the hardware connections for an Arduino-based Earthquake Detector with an ADXL335 accelerometer, an LCD display, a buzzer, and an LED indicator. The central microcontroller processes data from the ADXL335 accelerometer and controls the display, buzzer, and LED. Fig: Circuit for Earthquake Detector The article shows an earthquake sensor circuit idea which incorporates an innovative way of detecting the minutest of shocks caused by a possible earthquake tremor. The circuit is so sensitive that it is able to detect tremor of 4 on the Richter scale, yet remains unaffected to loud sounds or irrelevant bangs or noises. That is why I decided to build this Earthquake Detector. Step 1: Tools and Materials (x2) 741 OpAmps (Radioshack Catalog #: 276-007) The purpose of the magnet coil in this circuit is to detect when the hanging magnet from the cylinder passes over it. The magnet sways when the earth moves, triggering the piezo buzzer to sound, and the LED to

Circuit Description of Earthquake Detector and Indictor. The construction of earthquake detector is very simple and is shown in figure 2. It's employ few electronic components like arduino uno board, piezo sensor, LCD and buzzer with few passive components like resistors, variable resistors in order to work flawlessly. To make the shaker i will use a simple electronic circuit, Use DVD motor with its shaft attached to a pully and for the power supply use 18650 battery connected via toggle switch. Now you can glue this base of the house and to the roof add a drop of hot glue and place the vibration sensor. Tiny9 is back and today we are going to make a simple Arduino earthquake detector. So if I connect a 5V source to a 690 Ohm resistor and then to an LED to ground, the current in the circuit is going to be this: Example LED voltage drop = 2.5V (Source - LED) = Current * Resistance.

Earthquake Detector Alarm with Accelerometer & Arduino Circuit Diagram
Understanding the Accelerometer. The accelerometer measures acceleration forces (in g-forces) on the X, Y, and Z axes.For earthquake detection, we will monitor the acceleration values and determine if they exceed a predefined threshold, indicating seismic activity, Arduino triggers an audible alarm (buzzer) and visual alert (LED).
