Earthquakes can be dangerous and are often unpredictable. Seismic stations all around the world are measuring seismic activities. With the D7S module Omron created an affordable sensor that can detect ...

Tilt sensors are essential components in security alarm systems today. Standalone tilt sensors sense tilt angle or movement. Tilt sensors can be implemented using mercury and roller ball technology, ...

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

In today's lecture, we will design a project in Proteus, where we will Interface Gas Sensor with Arduino. I will provide the complete code and simulation. Gas sensors are widely used in fire alarms, ...

We built this Arduino-based Digital Thermometer for temperature measurement applications. Thermometers have been useful for temperature measurement for a long time. A digital thermometer is an ...
