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.

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:

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:

An essential part of the Internet of Things is having objects speak to each other wirelessly. Raspberry Pi’s are a great way to do this because of the low cost of available Wifi dongles and the ease of setting them up.

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.
