Tutorial 5# Smoke Sensor MQ2 with Arduino UNO.

[@immrnoidall]

i just used a 5VDC relay switch on with the AO. It can switch on anything up to 10 amps ,110/220 VAC ,OR 30 VDC. fan,light, buzzer. i have some computer fans hooked up to push air into my battery bank enclosure, in my camper, to vent out any gas if needed.

You are the best bro - thank you so much 🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼

[@pradeepgupta1190]

My MQ2 sensor detects only smoke but does not detect LPG

[@sanyamiri]

sir have you also done this with gsm module?

[@amiraabdulwanis8960]

sir, my sensor give me (1) if there is a smoke or not !!! in measuring digital output

[@williamwilliam4751]

thx for helping my project, may god bless you :)

[@ambedkarshmit]

Is this sensor is used to detect the fruit ripining.

[@kuldeepsinghkaswan5148]

no

[@irenicme8649]

How to connect motors to this circuit?
Please sir tell me I Making a project in school
The name of the model is smoke absorber

[@Ajith1810]

sir can i have that program in the video the last part is not clear!

[@kuldeepsinghkaswan5148]

int buzzer = 10;
int smokeA0 = A5;
int sensorThres = 500;
void setup() {
pinMode(buzzer, OUTPUT);
pinMode(smokeA0, INPUT);
pinMode(13, OUTPUT);
Serial.begin(9600);
}
void loop() {
int analogSensor = analogRead(smokeA0);
Serial.print("Pin A0: ");
Serial.println(analogSensor);
// Checks if it has reached the threshold value
if (analogSensor > sensorThres)
{
tone(buzzer, 1000, 200);
digitalWrite(13, HIGH);
}
else
{
noTone(buzzer);
digitalWrite(13, LOW);
}
delay(1000);
}

[@Ajith1810]

Thank u sir!

[@420ZEO]

sir kindly give the code to run the program the one you had given in comments is not working>>

[@kuldeepsinghkaswan5148]

this code is working correctly please check your connection

[@deepikagurung9410]

sir the coding is half

[@lifebytesss]

sir , what is (1000,200)

[@thortv1952]

how can u make this type jumper

[@zubairusmani6716]

Assalamualaikum so smoke detectors audios Arena closed circuit asmy Humne 3 sensor use karne Channel One channel to channel 3 May is complete informations Dekhe usme software kaise kiya jaye aur uski language Gaye Woh sari information Bataye Hum Kya Kare

[@zubairusmani6716]

Arduino Nano gadi hai usko Apna Humne 3 senses gas sensors used karni hai uske Ramya information program

[@nisargpatel5858]

Plz send the code's link

[@vellaengineer5776]

Sir my sensor itself dedect gas.whts problm.

[@kuldeepsinghkaswan5148]

check its limit value

[@k.a.ccrackerscrackers2669]

Vcc means

[@halojenlerflor350]

it means anode.

[@kuldeepsinghkaswan5148]

VCC stands for "voltage at the common collector." The letter "V" on a circuit stands for the supply voltage.

[@physicswithimranali7281]

sir please send a code thax

int buzzer = 10;

[@jenifersahana2021]

Pin this code sir

[@surajthapa2139]

Tq. .. Sir 😊
