CO2-sensor

Situation

This step-by-step plan shows how to program a CO2-sensor. This means that, if a set level of CO2 is detected during the day, an indoor siren will be sounded. If this occurs at night, the siren will sound and the lamps will also go on and the roller blinds will be opened. The siren can be switched off using a single push button.

Starting point

The starting point for this plan is a project which already encompasses Project information, which involves a signed or uploaded plan and where several inputs, outputs and actions have already been added.

Run through the steps in Adding a new project and then Drawing a plan or Upload a background image if there is no existing project.

Step 1: Create an action, "CO2-sensor"

Click on Creation at the top of the screen.

Click on add an action.

The action will appear as a text balloon on the plan.

Drag the action to a logical and appropriate place.
Give the action a name.
Choose the location of the action from the list of options.

If you wish to add a new action, click on add a location.

Click on continue to go to the players tab.

Step 2: Add an output to "CO2-sensor"

Click on add an extra output to add the indoor siren.
Click on other connected devices in the list of options on the right hand side of the screen.

The output appears on the plan.

Drag the output to the correct place on the plan.
Give the output the name Indoor siren.
Choose the location of the output from the list of options.

Click on save to go back to the players tab.

Step 3: Add an input to "CO2-sensor"

Click on add an extra input to add the CO2-sensor and the light sensor to the installation.
Click on analogue CO2-sensor in the list of options on the right hand side of the screen.

The input appears on the plan.

Drag the sensor to the correct place on the plan.

Give the input the name "CO2-sensor".
Choose the location of the input from the list of options.
Click on digital sensor in the list of options on the right hand side of the screen.

The input appears on the plan.

Drag the light sensor to the correct place on the plan.

Give the input the name Light sensor.
Choose the location of the input from the list of options.
Click on save to go back to the players tab.

Step 4: Choose players for the action "CO2-sensor"

Click on the lamps, roller blinds and indoor siren to link them to the action as players.
Click on continue to go to the basic behaviour tab.

Step 5: Determine the basic behavior for each linked output

Set the desired start and stop behaviour for every linked output.

The start behaviour in this example will be active when a set amount of CO2 is detected during the day. The stop behaviour is used to indicate what must happen if the same quantity is detected at night.

Click on continue to go to the conditions tab.

Step 6: Add a condition

Click on add a condition.
Give the condition a name.

Click on no (automation).

The action must start automatically if a set amount of CO2 is detected.

Click on the CO2-sensor and the light sensor to add them to the action as condition players.

These will be linked to the action via a black line on the plan.

For the CO2-sensor set the values you would like to correspond to the action.

Under advanced settings you will find a table containing all of the possible combinations between the various condition players.

Run through every column and click on the black button underneath to indicate what must happen in that case. You can choose between start, stop or slash (/).The option / (slash) means that nothing happens.

In this example, we would like the indoor siren to go off if, during the day, the CO2 sensor detects a level of > 600 ppm; in other words, the start behaviour is active. If this occurs at night, the siren will sound and the lamps will also go on and the roller blinds will be opened. In other words, this is the stop behaviour. In the truth table, this must be entered logically.

Click on continue to go to the time automation tab.
Click on save to return to the basic Creation screen.

Step 7: Add an input

Click on add an input to add the single push button to the installation.
Click on single push button in the list of options on the right hand side of the screen.
Drag the input to the correct place on the plan.

Give the input a name.
Choose the location of the input from the list of options.
Click on save to return to the basic Creation screen.

Step 8: Add an action

Click on add an action. The action will appear as a text balloon on the plan.
Drag the action to a logical and appropriate place.
Give the action a name.
Choose the location of the action from the list of options.
Click on continue to go to the players tab.
Click on the indoor siren and single push button to link them to the action as players.
Click on continue to go to the basic behaviour tab.

Step 9: Determine the basic behaviour

Set the desired start and stop behaviour.

In our example, the push button is only used to switch the indoor siren off. We therefore only use start behaviour.

Click on continue to go to the conditions tab.
Click on continue to go to the time automation tab.
Click on save to return to the start Creation screen.

Result

Now continue with Cabinet set-up and Realisation.
