How to display ANY sensor data in Blynk app | Blynk Help ...

If you can't get readings from the sensor without Blynk, you won't be able to send it to Blynk app 😕. Let's get started. There are two major ways of displaying sensor data in the app: PULL. In this case, Blynk app will request the data only when the app is open; PUSH. In this case your hardware will be constantly sending data to the Blynk Cloud.
