A common hacker upgrade to an espresso machine is to improve stability and performance with a better temperature controller, but [Schematix]’s Smart Coffee project doesn’t stop there. I… ...

This is the type of thing you could throw together with a microcontroller hobby board (i.e. Arduino and the related diaspora), a couple temp sensors (whether thermistors on analog pins or I2C temp ...

Maxim has announced a pair of temperature sensors, one accurate with an I2C bus, and the other with a multi-drop 1-Wire interface. MAX31889 is accurate: ...

After the temperature sensors detect deviance from the set point, or upon SMS instruction, the Freeduino will crank up the heat through a 5V relay attached to the home’s boiler.

It is described as an “open platform” that can collect temperature from multiple sensors, apply programmable control logic, and drive different loads with a precise PID algorithm. It is built around a ...

I used an LCD shield to display the current temperature and speed of the fan, but you can use the circuit without the LCD display. You also need to select the transistor by the type of fan that you ...

You'll need an Arduino along with a bunch of various sensors to get the project rolling, and once it's all set up you'll have a simple, but cheap system to monitor your home.

Excited by the idea of an open-source, Arduino-based outlet, capable of remotely controlling your various household devices? If so, you’ll definitely want to check out the Portlet: a versatile ...
