Arduino UNO:
The Arduino Uno is a popular microcontroller board used for various electronics projects. It’s often favored by beginners due to its ease of use and a wide array of resources available for learning.
Force sensor (FSR):
A force-sensitive resistor (FSR) is a type of sensor that changes its resistance based on the amount of force or pressure applied to its surface. It consists of a conductive polymer material that alters its electrical resistance when pressure is applied.
FSRs are used in various applications such as touch-sensitive devices, pressure-sensing pads, and in projects like force measurement, presence detection, or in your case, an anti-theft alarm system.
When connected to a circuit, an FSR’s resistance decreases as the force on it increases. This change in resistance can be measured using an analog input of a microcontroller like an Arduino. By reading this analog value, you can detect how much force is being applied to the sensor.
In the context of an anti-theft alarm system, you could use the FSR as a trigger. When someone tries to force open a door or window (where the FSR is placed), the increased pressure would cause a change in the FSR’s resistance, which the Arduino can detect. This change could then activate the alarm or trigger a response to alert about the potential intrusion.
