Build a presence detector with Spark Core

Dec 9, 2014 10:57:00 PM

By Luis Duarte H.

Want to know if someone entered your room? Sometimes a "Keep out" sign is not enough to keep out your siblings, so here we built a simple presence detector that lets you know if someone enters your room and how many times it happened.

As a cherry on top, we added an LED Matrix that displays a happy face when the room is quiet, and the opposite when it's not!

Building the Internet of Things using Arduinos

Sep 29, 2014 9:17:00 AM

By Agustin Pelaez

We love Arduinos as much as you do; which is why we got our hands on a few Arduino shields and made sure they were Ubidots-compatible.
Making Internet of Things projects had never been easier!

Logging Temperature and Humidity with Spark Core and Ubidots

Sep 8, 2014 1:05:00 PM

By Luis Duarte H.

The Spark Core is an open source, cloud-powered development platform. It's tiny but powerful, and it is easy to program because it's Arduino-compatible.

In this Spark Core Tutorial we will connect the Spark core to Ubidots, logging temperature and humidity variables in the cloud.

Turn a fan on when the temperature is too high! - Electric Imp Tutorial

Aug 26, 2014 3:35:13 PM

By Luis Duarte H.

In our last Electric Imp tutorial we learned how to measure temperature, humidity and overall thermal comfort with Ubidots. This time we are going to make a simple on-off fan control. We will log the temperature to Ubidots and trigger an event when it is over 30ºC, so that the Electric Imp turns on a fan, and then a trigger to turn it off when temperature is below 27ºC.

It really works like a charm, so here we go:

Logging Temperature, Humidity and Dew Point with Electric Imp

Aug 18, 2014 1:44:00 AM

By Luis Duarte H.

The Electric Imp is an amazing device for IoT projects and its integration with Ubidots makes it very simple to create graphs and SMS/Email alerts in a few minutes. This Electric Imp tutorial we'll teach you how use the Electric Imp breakout board with a DHT11 sensor to measure temperature and relative humidity, and then compute the Dew Point using Ubidots' math engine.

Control an LED remotely with an Arduino and Ubidots

Aug 18, 2014 1:16:00 AM

By Marcela Ramirez

This tutorial shows some of the basic capabilities of an Arduino and it’s integration with Ubidots. After doing it, you'll learn what an Arduino is, what it does and how you can set it up to turn an LED (or any other actuator) on and off from your Ubidots account. All you need to get started is an Arduino board and the official Arduino WiFi Shield.

What is Arduino?

Arduino is an open-source electronics platform based on easy-to-use hardware and software. The basic board can be connected to a series of devices to expand it’s possibilities; these devices are called “shields”. For this specific tutorial we will use the Arduino WiFi Shield.

Water your plants remotely using PiFace and Ubidots

Jul 28, 2014 12:36:00 PM

By Luis Duarte H.

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 monitor your Internet connection using OpenWrt and Ubidots

Jul 24, 2014 11:29:00 AM

By Agustin Pelaez

Is your Internet provider delivering a good quality service? If the answer is “no”, then how can it be measured? A nice way to get a sense of your Internet’s quality is to ping a remote host and watch the response times. This is what we call “Latency”.

This guide explains how to use an OpenWrt router to log the response times returned by the PING program, and send these times to the Ubidots cloud.

At the end of this tutorial, you should be able to create an embeddable graph like this - by the way, this is the actual data from our Internet connection!

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

Jul 16, 2014 10:51:00 AM

By Luis Duarte H.

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 like these:

 These are actually the environmental details outside our office!
