I’m doing some project IOT, but i dont know code send data from sensor to google sheet when using blynk app. can someone mine for share it?
sorry for my bad english
Maybe this will help get you started …

Thanks, btw when i run it and put blynk code my connection to blynk app was terminated, i can’t control anyting from blynk. Any idea?
@Shadeyman Haha 
… you started it 
Oh well… @Newbie1 We help you learn Blynk, not teach you how to program 
What you want to do is not a simple drop-in solution.
I suggest you click on the links at the top of this page (scroll up if you can’t see them) to the nearest Documents, Help Center and Sketch Builder pages, wherein you can to learn how Blynk works… This is a requirement in order to understand how to properly merge other code into functional Blynkified control.
As you learn about Blynk, we can assist… the rest is up to you.

i already build some project using blynk to controlling or send notification, i only need one more thing, storing data from sensor to database or google sheet. I already test local server blynk but not work, stuck in PostgreSQL
You could have led with that 
Blynk uses it in the Local Server, but we (the community) don’t “support” or teach how it works… for that you need to go to…
Is there are anyone have try use this? Using pushingbox to send data from sensor to google sheet
is there are any way to activated webhook not by button but when sensor active?
Your questions are related to this topic, so please don’t keep creating new topics.
You can send a webhook via button, slider, timer, function or whatever other method you chose via your code.
Of course.
Have you got the basic push button Webhook working?
Which sensor are you going to be using?
Yes
I’m using raindrop sensor with analog input
Assuming Webhook is on V0.
With BlynkTimer read the raindrop sensor at say 10s intervals.
Create the function that reads the sensor, like the PUSH DATA example, and do a virtualWrite() of the value to V0.
Got it, Thanks
Is there are any way to change the interval time Blynk push notification? Right now every 15s i get notification
15s is the minimum frequency for PUSH and email notifications.
You need to add code if you want it less frequently but you can’t have it more frequent.
Need add code in arduino ? I try to find in blynk doc but i can’t find anything about that
Yes in the section where you check the sensor reading. Set a flag and a timeout for the frequency of notifications.
