They used an Arduino to control the temperature and a motor shield to power the peltier plate. It kind of worked but they discovered it was difficult to assess the physical state of the chocolate.

This paper presents the development of a Arduino based Proportional-Integral-Derivative (PID) temperature control system using an Arduino UNO, R-type thermocouple, and solid-state relay (SSR) within a ...

Temperature-Regulation-with-PID-Control Read PDF file, It's the main file. This is my instruction of how to implement a PID control system to control temperature. Due to its modest scale, this project ...

PID control is a commonly used control algorithm. Elektor's new book is an excellent resource for anyone looking to use a Raspberry Pi 4 or an Arduino Uno in PID-based automatic control applications.

This is a replacement for the commercial PID unit he used on the original build. That monitored the temperature in the smoker, using predictive algorithms to maintain just the right heat level.

This paper presents the design of a frequency-based PID controller for temperature regulation around an LM35 sensor from a fan. The objective is to develop a frequency-based PID controller using the ...

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.

Arduino Nicla Sense Env is a new sensor module with temperature, humidity, and gas (TVOC, NO2, O3) sensing that follows the launch of the Arduino Nicla Sense ME (Motion & Environment) module over ...
