Proximity Sensor Library For Proteus Download

In this post I will discuss about the ir Proximity Sensor library for proteus and its simulation in Proteus. In the previous posts I have discussed the simulation of the other important sensors in Proteus. This post is oriented around the IR sensor, its working and the simulation in Proteus.

After reading this post the reader will learn about the IR sensor, working of the IR sensors and the simulation of the IR sensor in Proteus. The reader will also get to know about the simulation models of the components and the necessity of the simulation models in order to simulate the circuits.

Now let us discuss the simulation of the Proximity sensor in the Proteus. It is important here to mention that in order to simulate the behavior of any circuit in any software it is important that the simulation models of all of the components that are used in the circuit should be present in the library of the software. If the simulation models are not present in the library of the software that software will be unable to imitate the behavior of the whole circuit. The simulation models are the files that contain information about the behavior of the components. So in order to simulate the Proximity sensor the simulation model of the sensor should be present in the library of the Proteus. But the simulation model is not present in the library of the Proteus so we need to download the library first and then place the files containing the simulation model in the library of the Proteus. If you do not know about how to place the simulation files in the library of the Proteus go through my post on Ultrasonic sensor I have discussed the procedure there. The steps for simulation to follow are shown below:

I am Kashif Mirza, the founder of ProjectIOT123. I am an Embedded Engineer and working on Embedded Projects since 2003. I have worked on Arduino, Raspberry Pi, PIc Microcontroller, 8051 etc. and have designed both prototypes & industrial projects.

I am using ultrasonic HC-SO04, not giving reading on fabric. I lost many hours on testing my obstacle avoidance robot car in front of my sofa, every time it hits hard but works fine on other hard surfaces. Is there any other distance sensor which can detect soft objects like fabric from long or short distance?

If you are using HC-SR04 then I would suggest you to first check it out on simulation. I use Proteus software for simulation purposes and you should download the Ultrasonic Sensor Library for Proteus, using this library you can easily simulate your Ultrasonic sensor in Proteus and can design your code. It will save you from hardware testing.

Dear team kindly assist me on how i can get my circuit & / code to work to achieve the objective of displaying distance at which the cable is in open circuit after being cut by thieves. for my laboratory prototype i will use a twisted pair stripped from an ethernet cable to detect theft in ranges of 0,5m to 12m

i am using a capacitor to rep open circuited twisted pair cable in the simulation (using the fect that length and capacitance are directly proportional and the esd effect). On proteus the simulation is running fine , with some longer delay in outputing the freq and distance for 100pf or below.

Your image shows a frequency of 125 kHz, that's 8 s wavelength or 4 s per pulse (either high or low). This is going to require a bit more sophistication than the pulseIn() function which has a 1 s resolution.

You'll going to need interrupts and/or the input capture function of the timers. That way you can go down to 62.5 ns resolution for your pulse. This way you can also quite easily build a frequency counter that gives high resolution measurements of frequencies up to a few MHz (a modern 555 maxes out at about 3 MHz, which is getting close to the limit the Arduino can handle - if that's really an NE555 you're already over its limits with 125 kHz).

wvmarle:

One example of timing the discharge of a capacitor that I've written is for my EC sensor: GitHub - wvmarle/Arduino_ECSensor: Library to operate EC sensor for Arduino. It's using timer1, not the input capture method.

hello there , thanks for the code , i have gone through the code and i cant get how this will eventually help me to measure the lenth of my twisted pair copper cable in open circuit. if you could assist on this on

For your application you can simplify it as you don't have to worry about the second phase (steps 4-6 of the cycle), like when measuring the EC. One phase is enough. The other difference is that in my code the R is the unknown, in your case the C will be the unknown. That doesn't change the method.

Your cable has a capacitance, how much depends on the length. Cut it, and the capacitance goes down. The capacitance will be low, much lower than the 22 nF I'm normally using, so you need a large resistance, I guess somewhere in between 100k-10M, to get useful discharge times.

A reed switch is a type of electrical switch operated by an applied magnetic field. It consists of two ferromagnetic reed contacts enclosed within a glass tube filled with inert gas. When a magnetic field is applied, the reeds are drawn together, completing the circuit and allowing current to flow. When the magnetic field is removed, the reeds spring back to their original position, breaking the circuit.

Reed switches are often used in various applications where proximity sensing or simple on/off control is needed, such as in security systems, door and window sensors, flow sensors, and reed relays. They are valued for their reliability, long lifespan, and ability to operate in harsh environments.

A reed switch, which is triggered by magnets, functions as a simple switch suitable for Arduino projects. Similar to a conventional switch, it toggles on and off, but its unique feature lies in its response to magnetic fields. This characteristic makes it adept at detecting changes such as door openings within Arduino-based setups, offering a versatile solution for various applications such as home automation systems, security alarms, water level monitoring, and even interactive art installations.

In this illustration we will going to wire the NPN Inductive Proximity Sensor to detect metal or any metal objects, this device also can be used as a metal detector screening when people walking through the entrance to find metal objects.

This metal sensor are inductive sensors. Which means that it induces current when metal is near to it. This sensor is a non-contact electronic sensor that is used detect positions of a metal objects. The sensing sensing range depend on the type of metal being detected. Ferrous Metal, such as iron and steel, allow for a longer sensing range, while nonferrous metal objects such as aluminum, copper, can reduce the sensing range by 60 percent. Since the output of an induction sensor has two possible states, an inductive sensor sometimes referred to as an inductive proximity switch.

This sensor consist an induction loop, electric current generates a magnetic field, which collapses generating a current that falls toward zero from its initial trans when the input electricity stops.

The inductance of the loop changes according to the material inside it and since metals are much more effective conductors that other materials the presence of metal increases the current flowing through the loop. This change can be detected by sensing circuitry which signal pass true to some other device whenever metal is detected.

This device is commonly used in traffic lights, car washes, manufacturing machinery, automated industrial machinery, elevators and building automatons this device is mostly used because can adopt in a rugged and dirt environment.

The metal proximity sensor will have three color wire. The blue should be in the ground, brown is on +VCC which should be giving to Arduino + 5v VCC and when you take metal near tot the sensor it induces more current which results in higher voltage. In this case you need to open your serial monitor to see the incoming signal from the analog pin then make a threshold to determine if metal is detected or not.

Generally speaking the Iron/Copper or Metal with good magnetic properties will induce more that 1v when brought nearer to the sensor you need to touch the surface it will start detecting from a distance about 3CM.

It is up to you what range value to read from the sensor, in my case

i get the range greater than > 250, so if the sensor value above 250 then print {myOutput}

Previously in The Hacky Super Loop Arduino Nano 33 BLE Sense Example You Have Been Waiting For I attempted to address the lack of meaningful working examples for this board. The interfaces for each sensor are not always ideal, and no concrete examples are widely available that enable uses to utilise Mbed OS to gather sensor values.

The ability to use Mbed OS with Arduino is a real step up for Arduino. Finally, a reasonably performant and relatively deterministic way of arranging our more complex Arduino projects! In attempt to simplify the collection of sensor data and at the same time utilise the power of Mbed OS, Nano33BLESensor was born. 152ee80cbc
