A few weeks ago, I installed an automatic water heater switch to my bathroom, but it was a crude device. What I really want to do is design a universal heater driver. That basic idea can be adapted to ...

[Matt] wanted to have more control over his meat smoker so he built this advanced PID smoker controller. It uses the solid state relay seen in the bottom-right of this image to switch the smoker’s ...

Sous vide cookers aren’t anything new, but [Phil] wanted to build the first sous vide using the osPID, an open source PID controller just released in the last month. The build uses the osPID Open ...

A temperature controller is an instrument that controls temperatures, often without extensive operator involvement. In a temperature controller system, the controller accepts a temperature sensor as ...

(Editor's additional note: if you are not familiar with the principles and analysis of PID control: you should be; It is the most important, studied, understandable, and applied closed-loop control ...

The ABCs of PID control. Considerations for interfacing elements in the electrical circuit to accomplish those parts of the PID function for position control. Firmware code implementation.

The Dpi32 and CNi32 high accuracy series of 1/32 DIN programmable temperature/process meters and PID controllers feature RS-232 and RS-484 communications. These user friendly, easy to configure units ...

Maker, developers and hobbyists that enjoy building Arduino platform based projects might be interested in a new Arduino Motor Shield called the Arc controller which has been created by Arc Robotics.
