proteus-library-proteus
In Proteus, the library refers to a collection of electronic components, devices, modules, and symbols that can be used to create circuit designs and simulations. The library in Proteus contains a vast array of components from various categories such as:
Basic Components: Resistors, capacitors, inductors, diodes, transistors, etc.
Integrated Circuits (ICs): Operational amplifiers, microcontrollers (such as those from Atmel, PIC, Arduino, etc.), logic gates, analog-to-digital converters (ADCs), etc.
Sensors and Actuators: Temperature sensors, pressure sensors, motors, relays, LEDs, displays, etc.
Communication Modules: Ethernet modules, Wi-Fi modules, Bluetooth modules, etc.
Power Supplies: Batteries, voltage regulators, power sources, etc.
The library is an extensive resource that provides users with a wide range of components to build and simulate electronic circuits and systems. Users can access and utilize these components by dragging and dropping them onto the workspace, then connecting them to create the desired circuit.
It's worth noting that sometimes, if the required component is not available in the default library, users can create custom components or import third-party libraries into Proteus to expand the range of available components for their designs.
The Proteus library simplifies the process of circuit design and simulation by providing a comprehensive set of electronic components, allowing users to focus on designing and testing their circuits efficiently.

Now let learn more about IR Sensor
Infrared sensors
An infrared (IR) sensor is an electronic device that measures and detects infrared radiation in its surrounding environment. Infrared radiation was accidentally discovered by an astronomer named William Herchel in 1800. While measuring the temperature of each color of the light (separated by a prism), he noticed that the temperature just beyond the red light was highest. IR is invisible to the human eye, as its wavelength is longer than that of visible light (though it is still on the same electromagnetic spectrum). Anything that emits heat (everything that has a temperature above around five degrees Kelvin) gives off infrared radiation.
There are two types of infrared sensors: active and passive. Active infrared sensors both emit and detect infrared radiation. Active IR sensors have two parts: a light-emitting diode (LED) and a receiver. When an object comes close to the sensor, the infrared light from the LED reflects off of the object and is detected by the receiver. Active IR sensors act as proximity sensors, and they are commonly used in obstacle detection systems (such as in robots).
PIR sensors are most commonly used in motion-based detection, such as in-home security systems. When a moving object that generates infrared radiation enters the sensing range of the detector, the difference in IR levels between the two pyroelectric elements is measured. The sensor then sends an electronic signal to an embedded computer, which in turn triggers an alarm.

how-to-use-oscilloscope-in-proteus-part
The title of this video is How to use Oscilloscope in Proteus Part 2 Bangla 2021.
In this video, we are going to learn about Oscilloscope.
An oscilloscope, previously called an oscillograph,[and informally known as a scope or o-scope, CRO (for cathode-ray oscilloscope), or DSO (for the more modern digital storage oscilloscope), is a type of electronic test instrument that graphically displays varying signal voltages, usually as a calibrated two-dimensional plot of one or more signals as a function of time. The displayed waveform can then be analyzed for properties such as amplitude, frequency, rise time, time interval, distortion, and others. Originally, calculation of these values required manually measuring the waveform against the scales built into the screen of the instrument.
Oscilloscope History
The Braun tube was known in 1897, and in 1899 Jonathan Zenneck equipped it with beam-forming plates and a magnetic field for sweeping the trace.Early cathode ray tubes had been applied experimentally to laboratory measurements as early as the 1920s, but suffered from poor stability of the vacuum and the cathode emitters. V. K. Zworykin described a permanently sealed, high-vacuum cathode ray tube with a thermionic emitter in 1931. This stable and reproducible component allowed General Radio to manufacture an oscilloscope that was usable outside a laboratory setting.[3] After World War II surplus electronic parts became the basis of revival of Heathkit Corporation, and a $50 oscilloscope kit made from such parts was a first market success.
Description
An analogue oscilloscope, as shown in the illustration, is typically divided into four sections: the display, vertical controls, horizontal controls and trigger controls. The display is usually a CRT with horizontal and vertical reference lines called the graticule. CRT displays also have controls for focus, intensity, and beam finder.
The vertical section controls the amplitude of the displayed signal. This section has a volts-per-division (Volts/Div) selector knob, an AC/DC/Ground selector switch, and the vertical (primary) input for the instrument. Additionally, this section is typically equipped with the vertical beam position knob.
The horizontal section controls the time base or "sweep" of the instrument. The primary control is the Seconds-per-Division (Sec/Div) selector switch. Also included is a horizontal input for plotting dual X-Y axis signals. The horizontal beam position knob is generally located in this section.
The trigger section controls the start event of the sweep. The trigger can be set to automatically restart after each sweep, or can be configured to respond to an internal or external event. The principal controls of this section are the source and coupling selector switches, a

CIRCU
circuit-connection-and-vi
The P-N junction diode is appeared in the year 1950. It is the most essential and the basic building block of the electronic device. The PN junction diode is a two terminal device, which is formed when one side of the PN junction diode is made with p-type and doped with the N-type material.
The VI characteristics of PN junction diode in forward bias are non linear, that is, not a straight line. This nonlinear characteristic illustrates that during the operation of the N junction, the resistance is not constant. The slope of the PN junction diode in forward bias shows the resistance is very low. When forward bias is applied to the diode then it causes a low impedance path and permits to conduct a large amount of current which is known as infinite current. This current starts to flow above the knee point with a small amount of external potential.
PN Junction Diode VI Characteristics in Forward Bias
PN Junction Diode VI Characteristics in Forward Bias
The potential difference across the PN junction is maintained constant by the depletion layer action. The max amount of current to be conducted is kept incomplete by the load resistor, because when the PN junction diode conducts more current than the normal specifications of the diode, the extra current results in the heat dissipation and also leads to serve damage to the device.
