Please can you make a smart home bell project? 1. The camera records as soon as there is someone in front of the door 2. You can talk to the visitor 3. Send a notification to the phone immediately as soon as someone is at the door With raspberry Pi
Hi Sir, I have a question, the sensor is powered at 5V and the analog pin of the ESP32 supports up to 3.3V, how do you resolve this issue? Is it an error in the circuit or a lack of concept on my part?
to supplying sensor components or another actuator like relay, dc motor, and many more, you can adding with extra power supply like 5V battery (maks 9v) to activating.
Sir please help me I need same project but instead of gas detector I'm going to use DHT11 sensor and instead of buzzer I will use 2 channel relay. So whenever the temperature reaches above 35° one of the relay to be on state . Please help me sir
I tried doing this tutorial. I am using MQ135 and it works on detecting the gas. However, my buzzer doesn't make a sound when it sense a gas. I am using the same buzzer like on your tutorial but it didn't work. Pls help me fix it sir
@@MaahiBilliand is that red colour driver necessary ? I want to make a project of gas leak alert system. Ill use mq2. It senses and if gas leaks then it will send alert msg to thingspeak
@@MaahiBilli ok. Thank u for taking time and sharing info. Btw if u by chance have the source code for it then pls share it. It would be a very very big help, they have assigned a project which should be completed in 2 sessions only. And we got 0 info on that project since we have just entered engineering.😅.
Why doesn't my buzzer make a sound? if you connect to +, then there is sound, but if you connect simultaneously with mq-6, the buzzer will stop working
@@sritu_hobby I mean, you say it's ok to put the 5v analog range in a 3.3v analog range? I you put 5v in the analog input, even if it doesn't break, don't believe it's gonna be a faithful data

Sliding door glass otomatis and motor dinamo ac can you explained Master 🙇♂️...
Sir does gas gets trapped in the sensor ? As with 0 gas leak it still shows 19-20 fluctuating values on screen

Sir, can I get the reading on LCD when wifi is not available ?
pliss , I want a request to make an automatic door lock using nodemcu esp8266 with additional lc. You have previously made use of Arduino

Is lcd screen strictly necessary ? Want to make, gas sensor leak alert system. Is it compulsory to use lcd ?
No bro its not necessary
@Unknownperson-kd4zc ok♥️

@@mrgamer102-sl3bs Bro you can use only esp32 or esp8266 and mq-2. These two are must.

Sir, what's the unit of your reading
Thank you❤️❤️❤️❤️
You are so welcome
How to make schematic diagram out of this sir?.please
Does it detect fire and smoke too?
Yes
@@sritu_hobby sir plz give me the components link
Hi, great video
Just one doubt. The esp32 input pins support up to 3.3v. but the MQ2 run on 5v
How is it possible?
Its ok
@@sritu_hobby I mean, you say it's ok to put the 5v analog range in a 3.3v analog range?
I you put 5v in the analog input, even if it doesn't break, don't believe it's gonna be a faithful data
