Project to control the temperature of a greenhouse using ROS

• The project is done in c++ and it can be cloned from this repository

• To compile and run the project: make

How to run application

1. It will create the image

2. It will create the container

3. It will build the project using colcon_build

4. It will call the launch file that starts all the necessary nodes

Controlling the Temperature of a Greenhouse

In order to control the temperature of a greenhouse, we create four nodes: 1. One node for the controller, which will be listening to the temperature sensors topics 2. Two nodes for the two temperature sensors 3. A gui node to monitor the temperature progress and change useful controller parameters

Requirements: 1. If no temperature readings are available, the controller tells the window to be closed

Changing target temperature

Notice how the window openness changes throughtout the day, since the heat exchange (due to the sun exposure and the temperature gradient) also changes throughout the day.

Changing the PWM period

When choosing a smaller pwm period, the window set of available positions is smaller, and the command looks more “staircase-like”. Controlling the temperature with a smalle PWM period is still possible nonetheless.
