Matthew Reed writes: Therm RTD is an addition to the Therm PID Controller family, with support for RTD temperature sensors. RTDs (or Resistance Temperature Detectors) use a coil of fine wire made from a material (usually platinum, copper or nickel) that has a very predictable temperature coefficient of resistance (or change in resistance as temperature changes).

Therm: a Tiny PID controller
A tiny PID controller project from Ethan Zonca: Therm is a very small PID controller with an OLED display, thermocouple interface, and USB port. It can switch an external solid-state relay for driving large loads, or a transistor for driving small loads. When attached to a computer, it enumerates as a USB serial port for […]
Open source PID controller (DIY Arduino shield)
Tom posted his Arduino PID controller shield in the project log forum: Program a temperature profile to mash beer or reflow solder. Here’s how. This full featured open source PID controller uses a DIY stripboard shield for Arduino Uno and compatible boards. Firmware based on osPID massively revamped and extended, blood was sweated over new auto […]
osPID, an open source modular PID controler
The osPID is an open source modular PID controller. PID is used to monitor a process and provide feedback, such as the temperature controller on a DIY reflow over or sous-vide cooker. The main board has an Arduino and a user interface panel with an LCD and a few buttons. Two daughter boards are used […]
PID library for Arduino
Arhi tipped us to a PID library for Arduino. If you require precision control of electro-mechanical devices like heaters, servos, water pumps, etc. PID is one way to implement that control. It is an algorithm that controls a device by constantly adjusting its control or power signals to keep the device at preset state. Using sensors […]
