Automatic Door Bell using IC 555 Timer by Manmohan Pal
We can buy IR sensor from market or through online shopping sites but it costs us around Rs. 150/- here in this tutorial I am going to Show You how to make an Infra Red Obstacle Sensor under Rs. 25/- . The sensor which we are going to make is suitable for Arduino Projects and various other applications.

• How to make Infrared (...
Step by step tutorial to make IR Sensor
List of Items.
1) IC 555 Timer
2) IR diodes x2
3) Capecitor 100mf / 16 v x1
4) Resistor -2 1k, 10k,
5) NPN transistor BC 548/ 547
6) Buzzer
Lets Begin the Project, Mount the IC 555 Time in the center of the Breadboard and follow the steps to make connection between components.
1) connect Pin no 8 to positive Terminal of Battery (4.7 Volt Mobile Battery)
2) Connect Pin no. 1 to the Negative Terminal of the battery.
3) Short Pin no. 6 and Pin no.7 with each other
4) connect 1K Resistor between IC's Pin no. 7 and Pin no. 8.
5) Place a 100 mf capacitor between IC's Pin no. 6 and Pin no. 1.
6) Place IR LED between IC's Pin no.1 and 2 such that the cathode of IR LED is at the Pin no.2
7) Place another IR LED Between IC,s Pin no. 1 and 8 with a 1k Resistor at anode of IR LED.
8) Connect a resistor between Pin no.3 and Base of NPN tansistor BC 547.
9) connect the Emiter of NPN Transistor BC 547 to negative supply of battery.
10 connect the Collector of NPN Transistor BC 547 to the Negative terminal of the Buzzer.
11) Connect the positive terminal of Buzzer to the Positive terminal of Battery.
Now when an obstacle comes in front of both IR LED,s, the IR rays from Tx IR LED get reflected by the obstacle and reach the Rx IR LED. the IC 555 Time which is used in Monostable Mode get trigger (Low) at Pin no.2 thus it Provide High at Output Pin no. 3 . and the NPN Transister passes Negative voltage to the buzzer, while the positive voltage is already connected to buzzer thus the buzzer starts ringing. the timing of the ringing can be controlled by the value of the capacitor and the resistor between IC,s pin no. 7 and 8.
Circuit is complete enjoy the sensor with Arduino Projects.
Same circuit can be modified to Automatic Door Bel Circuit .
Same circuit can be used in reverse parking of Automobiles to detect the obstacle distance.

IR diode ke samne koi bhi obstacle na hi hone par bhi buser se bip ka sound AA raha he continuously kya karna ise sahi karne ke liye
TX RX ko ek dusre se dur kro, jyada paas hone se dirctly ir recieve ho rhi h
@@ManmohanPal vo bhi kar ke dekh liya kuchh ni ho ho raha
Koi or reason batao jisse me ise sahi kar sakunga
@@ManmohanPal What is tx and rx
I want a diagram for a four 200 watt speaker system that can play rock, classical, etc. of my choice when i push the doorbell. What do i need and how much you charge for the circuit diagram?
Can we do something with ldr in this circuit and make this sensor resistance to sun light?
For LDR i made another circuit, pls visit play list
Manmohan Pal I meant to say this sensor is sensitive to sun light, As Sun Rays also contains IR rays, can we add ldr and make this circuit work in sun light also
Can we use hw battery
Can we use 9V battery in place of mobile battery
Buzer continue bip kar raha he IR diode ko dur karne PE bhi kya karna padega ise sahi karne ke liye
Tx Rx k bich koi separater lagao ya dono ko thoda dur dur lagao
Manmohan Same problem. In ko dooor krna sa b buzzer continuesly beep kr rhi ha
@@qasimnisar2800 chk power supply it should be not more than 5 volt
Same problem continues baj Raha h
Please tell me best solution
can we use ir module for this?
IR diode (transmitter,receiver )Jo use kiye he unke pure nam kya he sir
IR diode.... simply Ask for Remote LED..

Thank u sir
u hv mentioned its price is reduced to 25 rupees ,how ?
Iska PCB circuit diagram batiye sir
Sir isme total kitna kharch ayega
Can u please give circuit diagram
I make this circuit but it cant work i think this video is wrong
You failed an exam mean text book was wrong
I can send my circuit photo in your WhatsApp Check whats wrong... Why my circuit can't work
Circuit diagram kiyun nahi dikhate ho
is ke pahle video apne jo upload kiyi hai wo, del kr do sir , jisme buzzar connect nahi kiya hai, us video main apne wo last wala rasistor ke baremin nahi banaya is liye wo work nahi krta
Sir I want components name's
Thanks sir ji
Transistor ke base SE Jo resistor connect he uski value kitni he sir
100 ohm se 330 ohm k bich ka koi b lelo
Dear sir,
Can I use a TSOP 1838 IR receiver in this project?
TSOP 1838 can't continuously receive the IR signal. It reads the signals in burst. Hence I asked this questions.
Can you show me

Bhai 3 resister he
Circuit diagram?
Circuit diagram plzz
Sir circuit diagram?
Sir Circuit Diagram Bhi Bhejho na
@Manmohan Pal
nice
Circuit diagram
Auto water tap video dalo sar
Thanks for idea I will do it for u

O bhai ans nh dete to channel leave kr den
Mene kai bar poch k bro is circut me buzzer ya light ko ma 5 second tak on rkhna chata hun plzzz
Sir I've send you a message please reply on your whatsaap
Can you share the circuit diagram
