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.


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.
