- IR-Sensor USING LM358 ( MakeloGy )
Introduction
Infrared technology addresses a wide variety of wireless applications. The main areas are sensing and remote controls. In the electromagnetic spectrum, the infrared portion is divided into three regions: near infrared region, mid infrared region and far infrared region.
The wavelengths of these regions and their applications are shown below.
Near infrared region - 700 nm to 1400 nm - IR sensors, fiber optic
Mid infrared region - 1400 nm to 3000 nm - Heat sensing
Far infrared region - 3000 nm to 1 mm - Thermal imaging
The frequency range of infrared is higher than microwave and lesser than visible light.
For optical sensing and optical communication, photo optics technologies are used in the near infrared region as the light is less complex than RF when implemented as a source of signal. Optical wireless communication is done with IR data transmission for short range applications.
An infrared sensor emits and/or detects infrared radiation to sense its surroundings.
The working of any Infrared sensor is governed by three laws: Planck’s Radiation law, Stephen - Boltzmann law and Wien’s Displacement law.
Planck’s law states that “every object emits radiation at a temperature not equal to 00K”. Stephen - Boltzmann law states that “at all wavelengths, the total energy emitted by a black body is proportional to the fourth power of the absolute temperature”. According to Wien’s Displacement law, “the radiation curve of a black body for different temperatures will reach its peak at a wavelength inversely proportional to the temperature”.
The basic concept of an Infrared Sensor which is used as Obstacle detector is to transmit an infrared signal, this infrared signal bounces from the surface of an object and the signal is received at the infrared receiver.
There are five basic elements used in a typical infrared detection system: an infrared source, a transmission medium, optical component, infrared detectors or receivers and signal processing. Infrared lasers and Infrared LED’s of specific wavelength can be used as infrared sources. The three main types of media used for infrared transmission are vacuum, atmosphere and optical fibers. Optical components are used to focus the infrared radiation or to limit the spectral response.
Optical lenses made of Quartz, Germanium and Silicon are used to focus the infrared radiation. Infrared receivers can be photodiodes, phototransistors etc. some important specifications of infrared receivers are photosensitivity, detectivity and noise equivalent power. Signal processing is done by amplifiers as the output of infrared detector is very small

Infrared Transmitter is a light emitting diode (LED) which emits infrared radiations. Hence, they are called IR LED’s. Even though an IR LED looks like a normal LED, the radiation emitted by it is invisible to the human eye
IR Receiver
Infrared receivers are also called as infrared sensors as they detect the radiation from an IR transmitter. IR receivers come in the form of photodiodes and phototransistors. Infrared Photodiodes are different from normal photo diodes as they detect only infrared radiation. The picture of a typical IR receiver or a photodiode is shown below

Your explanation is too good than other youtubers.
Im not a beginner but I do not understand. You have made receiver or transmitter or both ??? Do you intend to use it as a receiver or transmitter depending on the need?
Thanks for giving knowledge
good one bro
Ye photodiode kya remote ma mil jaya ga?
Hi friend. Détection distance please.
Fabulous sir
Nic one bro
Kya hmm. Is Circuit se Ghr ke light ko on Ya off kar sakte hai.
can i use ir reciver 1738...if yes then why...
if no then why...
How long it can sense.
can we use this to count heart beat
Love This..!!
🥰
i’m always watching you..:
😊
keep it up 💖'
superbly explained Sir, good job! I had an IR module , I attached a 5 vmotor pump to it using a TIP32C transistor, Output from module is attached to base of transistor, VCC 5v from power source & module to the Emitter & positive line from pump to collector, when the current is switched on it makes the pump to run continously , It , however slows down when an obstacle is brought near the IR transmitter / Photodiode, is there something wrong with the IR module? I was trying to make an automatic soap dispenser
I found the solution to the problem, I realized there are two types of IR module in the market , one with single LED which works well with BC 457 transistor , as shown in your schematics & other with Two indicator LEDS, which works well with TIP32C /TIP 42c
Line follower kahan hai apka?
Distance???
Aapne starting me blue led ko photodiode bataya lekin bad me usko IR Receiver bata kar connect kara kya sahi hai shayed tabhi ye kam nahi kar raha don't make fake video plz
Maine ye banaya ha lekn ye sunlight Mai direct Kam KR RHA ha or night Mai sahi Kam KR RHA ha Maine is ko shade bhi provide kra ha phr bhi Kam nhi KR RHA.
Main problem is you can't use it at sunlight
It should be partition between diodes.
3 leg ki ir reciver ka fitting bataya. 2 leg reciver no avelable. TSOP1738 AVAILABLE
Plz make levitation anti gravity
Bro here one thing is wrong that is it led's negative will be connected with resistor and then to ground
Show it working.
Bhai sabji Muje viring patanahi kese karane gi
Nice technic...bro
Thanks bro
Add it's working
Sir 24 vdc main banao
You did not test ur work!!!!
What is the difference between output and ground??
Ground -ve supply
Output sensors signal for device
@@MakeloGy so what should I connect at output in the circuit??
Manoj Kiyan , you can drive bigger load with transistor and relay connection
In this pin sensor provide you output so that you can use anywhere .. like feedback of This sensor .
Using this signal you can find distance, line follower ...
@@MakeloGy but the IR reciver have only two legs(+ & -)
Lm358N/Lm358p???
What is the difference
Surya ke Prakash ko accept na Karen Aisa koi upay bataen
Gher me chalao 😁
Try this one forum.arduino.cc/index.php?topic=134089.0
Why you are wasting opamp when you can use NPN transistor. It will create your project cheaper.
Why didn't you test it. I used the same schematic but didn't work waste of time
Keya ye kaam nehi kar raha...
Ek baar jaala k dikhana chahiye tha...
Tum par se to mera varosa uth geya...
Speak slowly brother
Ok i will remember this thanks
