[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 ...

[Jason] learned a lot by successfully automating this meat smoker. This is just the first step in [Jason’s] smoker project. He decided to begin by hacking a cheaper charcoal-fed unit first, before ...

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 ...

The reactive controls we discussed in Part 1 are driven entirely by error. This is a bit like driving a car while looking out the back window. Your mistakes may be ...

Starting with the sensor, measuring and controlling temperature is an essential building block of process industries. Automatic control in continuous processes uses industrial control systems to ...

Machines and processes are controlled using many strategies, from simple ladder logic to custom algorithms for specialized process control, but proportional-integral-derivative (PID) is the most ...
