Embedded Systems - Control temperature on/off

The objective of this application is to control the temperature, inside a controlled environment, using an on/off mechanism: a resistor heats the environment while a cooler chill it, the control is done turning them on or off. The whole mechanism is described with more details in this description.

Demonstration

The application in execution (and window from the live with the equipment):

Relevant attributes

Abbreviation	Attribute	Description
TI	Internal Temperature	Temperature inside the controlled environment
TE	External Temperature	Temperature of the room
TR	Reference Temperature	Temperature which the system will try to achieve

Features

• Hysterisis input by user
• Runtime update of desired temperature through keyboard or potentiometer
• CSV generation with recorded values
• LCD display shows values
• Terminal shows values

Building

The code was developed and tested in a Raspberry Pi.

External dependencies

These are dependencies which are not cloned with this repository:

• WiringPi

Building

1. Clone the repository:

git clone --recursive https://github.com/icaropires/embedded-temperature-on-off

2. cd into project's dir and build it:

cd embedded-temperature-on-off
make

Running

At the project root:

make run

A file errors.log will be created to keep possible error messages to stderr.
