- Blynk app enables us to monitor the values … Blynk app enables us to monitor the values recorded by the weather station remotely, directly on our smartphone, regardless our distance from the weather station. All we need is the blynk app and an internet connection. In this project you’ll learn how to monitor the values recorded by the LDR sensor and the DHT11 sensor only. == Create a new project in the Blynk app == After you’ve download the app and you’ve successfully logged into your account, start by creating a new project. == Choose Your Hardware == Select the hardware model you will use. If you are following this tutorial you ll probably be using an ESP32 board. == Auth Token == '''Auth Token''' is a unique identifier which is needed to connect your hardware to your smartphone. Every new project you create will have its own Auth Token. You’ll get Auth Token automatically on your email after project creation. You can also copy it manually. Click on devices section and selected required device: And you’ll see token : == Set up the Blynk app == You will need to create a project on blynk which is tailored for the purpose of monitoring the parameters recorded by the weather station. Grab 3 value display widgets. Configure them one by one. The first will receive V6 as input, the second V5 and the third V0. You ll notice that they re all set to push mode. notice that they re all set to push mode. +
