Eric Edwards of EJESolar.com created a system that takes solar energy and heats water for his home. He uses Sun Strip Solar panels to heat the water. With a single solar panel Eric is able to heat a 60 gallon tank to temperatures beyond 160°F. He uses the ioBridge IO-204 to data log and actively monitors the water heating system by getting alerts and updates on his mobile phone.
Water Tank and ioBridge IO-204
ioBridge IO-204 with Temperature Sensors
Eric monitors and data logs the temperatures of the the hot water storage tank, the collectors, and the outside temperature in real-time using the ioBridge IO-204 and temperature sensors. This data allows Eric to calculate BTUs collected per day and translate into a dollar figure to track savings. He has surrounded himself with the data to make sure there is no system damage, freezing, etc., by creating a web site to view the data, setting ioBridge message alerts, and using a Google Gadget to display the temperatures collected by the IO-204.
Visit EJESolar.com to see a live view of the data collected by the solar hot water system as well as some more details behind this solar hot water heating system. Ingenious!

ioBridge offers a web-based platform for interfacing the physical world. You can connect sensors, switches, and controls to the IO-204 module and send email, update your Facebook status, or let your friends know what your power usage is on your blog without touching a single line of code. If you can click, you can create.
The IO-204 connects to your network and establishes a link to the ioBridge web services in the “cloud”. From there you can control, monitor, and share by using a point-and-click design interface or through open APIs.
We have released a new firmware called C4.0 which allows you to go beyond the cloud. C4.0 is an explosion of new features. You can create projects and products that work with the network cable unplugged. Using the ioBridge.com interface, you design rules and synchronize those rules to the module. Now, with or without the Internet connection, the module can make on-board decisions, turn fans on, control your lights, and sound buzzers.
The C4.0 firmware also includes high-frequency pulse counting. You may be asking yourself, “Why does pulse counting matter?” Well, pulse counting allows you to track inputs that are going on/off, around, or up and down. You can count the revolutions of your power meter. If you know how many times it spins around, you know how much power you have used. You can count the revolutions of a windmill to calculate wind speed. This feature keeps counting even if your network connection is not available.
Here’s more great news…If you already have the IO-204, you can upgrade your module to the new firmware by clicking upgrade on the module section of the ioBridge.com interface. All new orders ship loaded with C4.0 so you get all of the new features right out of the gate.
Details regarding the new firmware are available in the ioBridge Wiki. We are excited to see what you come up with!
A number of ioBridge users created some amazing ioBridge-based projects for this Halloween. We were impressed with the diversity and how they interacted with the IO-204. From using some new offline features of ioBridge to using social networks to poke fun at their Halloween prey.
We have a steam powered steampunk pumpkin that blows smoke out if it’s ears. We have a spider dropping on it’s victim and snapping a photo and posting to Twitter via TwitPic. We also have a motion sensing, talking skull that scares co-workers in the owner’s cubicle. Check them out!
From the “My Electronics Notepad” blog, Noel Portugal created a tracking webcam using passive infrared (PIR) sensors, a webcam mounted on a servo, and the IO-204 monitor and control module.
PIR Sensors, Webcam, and ioBridge IO-204 Module
Noel was able to pull this off with using the ioBridge Actions. An action is logic created through the ioBridge interface that allows automated events to occur. For example, an action can cause a servo to move to preset position, send an email, update your Facebook status, etc. In Noel’s case, he use the output of the PIR sensor to cause the servo to move to a set position. The output of the PIR is digital – “high” means motion detected and “low” means no motion.
Using two PIRs covering two regions, he was able to detect motion in two regions. If motion is sensed in one area, the webcam points in that direction and if motion is detected in the other area, the servo moves the camera to cover the other region. Very clever.
The PIR sensor has been the subject of a recent Adafruit tutorial – it’s available on the Adafruit store and even your local Radio Shack (of all places). For more information about this ioBridge project and other projects Noel dreams up, visit his blog.
Thanks to Oprah, Twitter is a household name. You can’t avoid it. But, Twitter uses are starting to flourish thanks to an API and dedicated developers. Matt Morey has developed a two-way, home automation application using Twitter to control lights and LCDs and monitor temperature and light sensors. His app interfaces Twitter with the ioBridge IO-204 by using the PHP Widget Control API.

Matt’s Twitter application allows him to make updates to his Twitter feed and send commands to his IO-204 to turn on lights, send messages to his serial LCD screen, and get temperatures and light sensor readings. He also has a nifty extension that allows you to see a view from his office by sending him a tweet, which takes a snap shot from a digital camera and posts it on TwitPic.
