IoT Interfaces Made Simple With Nextion, Raspberry Pi and Ubidots

Have you heard about Nextion Display? Nextion allows you to craft awesome interfaces, even if your coding level is “hello world!”. Its awesomeness doesn’t end up here. It can work with Arduino and all versions of Raspberry Pi. 

This tutorial will show you how to add a Ubidots button to your Nextion Display Interface.

Hands on the AirPi Kit v1.4, a weather station using Raspberry Pi

AirPi is an plug-and-sense, low cost weather station. It works as a shield for the Raspberry Pi, gathering data about temperature, humidity, air pressure, carbon monoxide, nitrogen dioxide, light levels, noise levels and even more. In this article we’ll connect the AirPi Kit to the Ubidots cloud, creating a connected WiFi weather station.

Once the AirPi is plugged to Ubidots, you’ll be able to create a real-time widgets in Ubidots Dashboard.

Results: Using a Raspberry Pi Model B we can display these actually environmental details outside our office. With Ubidots you can monitor your environments.

Water your plants with a DIY Smart Sprinkler using PiFace and Ubidots

One of the reasons I mostly have cactuses at home is because I often forget to water my plants. This is why I build this project to control an electrovalve remotely to irrigate my plants from any place just using my phone.

At the end of this tutorial, you should be able to do something like this:

How to build a parking sensor to solve the pain of finding a free spot

In this project we’ll build a simple parking sensor using a Raspberry Pi. It turns out that every morning I have to face this question: is the ONLY parking spot in front of my office already taken? Because when it actually is, I have to go around the block and use at least 10 more minutes to park and walk to the office.
So I thought it would be cool to know whether the spot is free or not, before even trying to get there. At the end, the result was a nice widget that I could check from my Ipod or mobile phone:

Building a People Counter with Raspberry Pi and Ubidots

12855755553_4b9e885e72_z
People counters are mostly used in the retail industry to gain better insights of how shoppers behave. They are also found in security, event management and smart cities applications. Imagine you manage a large mall; these counters would help you know how many people enter your mall, which paths they take, where they stop, and foremost, when does it all happen.
Just like most sensors, people counters have been around for a while. However, their data is not always centralised and connected to enterprise systems where they can support decision making.
