Luar biasa banyak fiturnya terimakasih banyak selamat dan sukses buat Srituhoby semoga ilmunya berkah. Amiin
thank you for the video, can i use only one sensor ? if so should i keep only the part of the code that concern the sensor i want to use ?
Hello Sir, I am facing issues with relay.
My relay is getting NC to NO.. on applying both 3Volt and ground
When I touch input pin of relay to 3volt of nodemcu it gets switched... And if i also connect it with ground pin of nodemcu..it also switched on
Great, can you upload a QR code for Blynk?
If I want to make this as final year project but would like to put it all together in a more professional setup how can I do that
Can't we connect these devices remotely with the hub, only power will be providing to device and balance communication through wifi etc
Hi, me again...my MQ2 is crazy, I don't know why, I don't expose it to gas and it makes readings over 600 or more ,then it goes down to 0 and 2 seconds later it goes up again, I see the graph in Blynk, I have tried with many PINS but it still doesn't work properly, can you help me? should I calibrate? thak you!
hello mr ihave a little problem....the pir sensor keep running on even if no thing around can you till me where the mistake
hello, i tried it everything is working perfect but firstly the lcd showed temprature and humidity but now it is not showing them. and the compiler is giving me some error crystallibrary run over avr and not compatible with esp8266. everything else is working fine
hi, what is the size of bread board because my nodeMCU covers A-J everything ? No, holes r left to connect jumper wires ??
can u try these sensors with new blynk application?
Can I make use of google assistant and alexa for voice activation?
what kind power supply do you use?
1 nodemcu esp card or wemos d1 mini card 4 or 5 sensors
Hii, i want to add 4 channel relay in this project along with all other sensor but all digital pin are full , is it possible to add ??
It's not possible
It is showing error that pirsensor was not declared in the scope, Can u please tell how to resolve this issue?
Hi, How can I use with the new BLYNK 2.0 app. excellent idea I encourage you
For that check my other videos. Or srituhobby.com
Thanks a lot of
sir only my gas sensor is working properly other sensors and not working smoothly can you tell where i might have made mistake
yes i also encountered the same problem
Ye Smart home ka project he?
Can you share the download link for the app "Blynk"
hi, is it possible to do the same project but with 4 relays?
Digital PIN limit exceeded
@@sritu_hobby okk , thanks a lot
Hey sir, are you have a tutorial for blynk to WhatsAp notification?
No bro.
Please , tell me sir
Can i use 44.4volt battery??
Don't use
Sir, can i use 44.4volt battery in this project
Please, tell me sir
Can i use another nodemcu esp2866 model other than cp2102?
Yes of course
Can you please show this with blynk IOT as blynk legacy is not usable anymore. Im trying with blynk Iot but its very different
Check our videos
Can I make this project and google assistant home automation project in one using single Node mcu. Is it possible ?
Yes, you can do it.
@@sritu_hobby how? Can you help me because i don't know lot about coding
Sir even if i disconnect my pir sensor or turn off the buzzer keeps on ringing non stop please help kardijiye🙏🙏
Mere LCD vale code me error aara. Can u help me?
Check you program
I have downloaded ur code file and then open it with IDE and include the libraries which u have given? What else i have to do? I have my project submission please let me know
hi, is it possible to use esp32 instead of esp8266?
Yes of course
Hello bro... The program was uploaded in wifi module and it was connected with my wifi but the blynk app didn't show my project is online . I cheeked with serial commication in arudino software it shows a "Invalid Authtoken" pls upload aa video for this error
Please check your WIFi details and autk token
Bro, change your ID and Wifi password . after this, try again. It Will Work.
can I use ESP32 instead of ESP8266?
Nice... Great job btw, thank you!
Where you put the last 2 wires using the alligator?
External power supply
pls help me!! My LCD just light but not showing anything, what should I do now ?? :
Check jumper wires
Display doesn't show anything except the backlight and it keeps blinking and the buzzer just keep ringing. Checked all the wires. Can you please help?
Please provide a external power supply
@@sritu_hobby Hai, how to connected the power supply to esp32, expecially for power supply 5V 3A.
Connect it VIN and GND pins
@@sritu_hobby no i mean, how to connect the cable to the power supply
Can i Use 45volt battery
9v
Ok , sir
i didn't get the code
Sir code dijiye
gas alarm fire alarm dht11 sensor and relay manual switch open closed warning bylink 2.0 compatible 4ın 1
