Mature Arduino Engineering: Making an Alarm System Using the Arduino
In this chapter we will be creating various pieces of a motion detecting alarm system using the Arduino. To satisfy our example company’s requirements, the alarm system will track any motion detected throughout the day and store it on a microSD card. The company also wants to have real-time tracking, so the information will need to be displayed on the Serial Monitor.
To do so, we will be learning about a new piece of hardware called the passive infrared (PIR). We will also be using an ultrasonic sensor in order to create a different type of security system. Our preliminary project uses an ultrasonic sensor as a door alarm. This will prep us for the final project, ...
