Just like the flex sensor the light dependent resistor is also used in the voltage divider configuration, the resistance of the LDR sensor alters as the intensity of light projected on the sensor varies. The LDR sensor is the abbreviation of the Light Dependent Resistor and as the name implies the resistance of this sensor varies in relation to the intensity of light, greater the intensity of light lower will be resistance of the LDR sensor. The PIR sensorin the Proteus looks like in the following image:You can download the simulation model of the PIR sensor from the following link. So when the object comes in its field of view the readings of the sensor gets disturbed and thus detect the presence the object in front of it. PIR (Passive Infrared) sensor is also commonly known as the motion sensor which measures the Infrared (IR) light radiating from the object in its field of view. You can download the simulation model of the flame sensor from the following link. The flame sensor in Proteus looks like in the following image. The fire sensor also consists of the operational amplifier which conditions the measured signal so that microcontroller can easily read the signals and successfully process the signals.

The fire sensor detects the presence of the fire by detecting the IR (Infrared Radiation) waves present in the fire. The flame sensor also known as the flame detector is a type of sensor that senses the presence of the fire in its vicinity.

In short you must have the simulation models of the components in order to imitate their actual behavior.

If you have the component in your circuit whose simulation model is not present in the library of your software then the software will be unable to simulate the behavior of the circuit.

While simulating any circuit it is important to keep in mind that the simulation models of all the components that are being used in your circuit or embedded system must be present in the library of the software.

There are a lot of the software and online tools available for simulating the circuit or embedded systems, among them Proteus holds the significant position which is equally popular among students and professionals.

The simulation software calculates the behavior of the circuit by calculating the mathematical equation of all the components.

Let us now summarize all the custom made simulation models required for simulating the embedded system designed based on the Arduino microcontrollerdevelopment board.In this projectiot123 tutorial we will Learn the Download Proteus Library of Components.The simulation model of an electronic component contains the information about the input and output relationship of the electronic component in the form of the mathematical equation.
