TRANSCRIPT:
In this video, I am going to explain to you how to make a smoke detector circuit. Let's get started.
Here is the circuit you can download from the link given in the description.
Connect movable contact of the 10 Kohm potentiometer to 3rd pin of the IC LM358
Connect 4th pin of the IC moc7811 to one of the fixed points of the potentiometer
Connect 3rd pin of the smoke detector sensor to a 100ohm resistor and connect movable contact of the 4.7 k ohm potentiometer to its fixed terminal and another end of the 100-ohm resistor
Connect 33k ohm resistor to 2nd pin of the smoke sensor and 2nd pin of the IC LM358
Connect 100 k ohm resistor to 1st pin of the ic LM358.
Connect another terminal of the resistor to the base of the transistor BC547
Connect 10 Kohm resistor to collector pin of the first transistor and base pin of the second transistor
Connect the negative terminals of the led and buzzer to collector pin of the second transistor BC547
Connect the 680-ohm resistor to +ve terminal of the LED
Connect 4th pin of the ICLM358 to -ve pin of 100 µF capacitor
Now connect the Vcc and ground to the components as shown
Connect the battery clip to the Vcc and ground
Connect the battery
Here you can see when the smoke detector detects the smoke then LED and the buzzer will switch on. Make sure to adjust the variable resistors to detect the smoke by the sensor.

Wonderful technique

[@aumkataria3389]

Sir can we construct this same circuit you have given in description in bread board ??

[@aranyabiswas141]

It's the best one.... I made it and works completely fine ❤️

Sir Question can we use 2200uf so buzzer have delay sound?

[@nileshpandit4577]

Sir Maine aabhi smock detector project banaya hai lekin buzzer or led band nahi ho rahi hai
