Actually I am making this better with more sensors and using node red.. And will post a new project soon Stay tuned for that..

Just check if the baud rate of esp01 is same as which u declared in sketch for th communication.. And also try to reboot it or upload the latest firmware for esp.

in code u have not used Wifi.begin() and Wire.begin() howcome the wifi module get connected and how will the i2c start? please calrify

the wire.begin() is done by the bmp.begin() handeled by the library and the wifi.begin() is done by the Blynk library...

Since Tweeter is free, can it be possible to use Tweeter to inform of the status of the machine?

Ya Sure! Blynk has the availability to use twitter also.!

Well, I wonder how much fires are you going to cause using your equipment when detecting "flammable gasses". Please reconsider using your setup in potentially explosive environments.

There won't be any such huge fire to burn down the whole industry. For protection over voltage and current protection can be also added. Thanks for suggesting this will improve in next prototype.

hi vimarsh...how many blynk energy need for this project..??
vimarsh

I think it's more than 2000 what u get free.. but don't worry make your own one. Just see the code and change the different stuff u need.. add simple value displays rather than the chart which needs more energy.. I am making a better one which doesn't use blynk but node red which will have better UI and no restriction

Suggestion: Use a BME280 and throw the DHT11 in the trash. Maybe use the new BME680, which includes a "gas sensor".

Thanks for the suggestion... I had planned to use it but it's not available in India at proper price and still it's costs more than two bmp280s and Dht 11s... And the sensors I have used are still not precise enough for industries. So they would have to be replaced with industry grade sensors(which are costly for prototype)..

Hey , amazing project, can you add jpeg camera , magnetic door lock and use lets say sim800l ? considering lack of internet in many places, that is send sms notifications>?
