This is a short tutorial for connecting and setting up the MH-Z14A carbon dioxide sensor in Arduino w/OTA updates and Blynk.

If you have ever wondered how to get started in the IoT (Internet of Things) world, this is the tutorial for you!

Create your Blynk mobile app to monitor your garden and activate the irrigation.

Collecting multiple data from multiple sensors connected to the same 1-wire bus and monitoring them from the internet with Blynk.

Every time a movement is detected by the sensor, a message is sent to a smartphone anywhere in the world!

Display sensor values (DHT11 in example) on the Smartphone using Blynk App.

Build an Android or iOS app for your hardware with no coding!
