DIY Humidity/Temperature Monitor With Blynk

Experimentation with new things is not bad especially when they are paving the path of progress. In this project, we are dealing with Blynk, an amazing iOS and Android app that permits the users to connect any hardware with this application. The basic idea behind this app is to give shape to the idea of a smartphone that allows the users to drop and drag buttons, graphs, functional widgets, and other display icons. Within moments, the widgets are able to control and acquire data from any Photon, Particle Core, Raspberry Pi and Arduino. This project is a small step towards it. 

 

 

The creative head behind this project decided to integrate Blynk with a basic project meant for monitoring humidity and temperature of a given place. The DHT22 has been plugged in the Particle core. There is one more tool that comes as a standard offering with the Particle wifi dev kit, the Particle dashboard. You can imagine a virtual cable connected to the internet from your personal Particle with the search engine. You can always keep a check on the published events without any wires via Particle. 

 

There is one small restriction with Particle, it doesn’t allow the user to add controls or improvise the trigger functions or variables in the Particles. It is one of the most common points mentioned by its regular users. If you wish to control your project through tablet or phone, you can always code an app all by yourself. The Particles team offers SDKs for iOS as well as Android. The Blynk team, on the other hand, crated a completely different cloud where different types of hardware can be connected. That is one feature that makes this project an awesome one. 

 

You can always download the Blynk app from Google Play Store and create a completely new account. You can visit the Particle IDF and add the Blynk library to your Particle firmware, add some more coding lines to expose the variables to Blynk cloud and flash the new code to the dev kit. For adding some widgets to this app, you can always get a gauge and a value display. 

 

With the help of this setup, you can always add the Android app to any project within 30 minutes. Variables like temperature and humidity will be on your tips in a neat fashion saving countless hours of Java programming with respect to Android. Blynk also allows you share your project with others and paves the path for integrating the same with their projects. For schematics and coding details, you can click on the link given below.
