Aggregate

An aggregating function is a calculation performed on multiple values in a given time interval, returning a single value. Displaying each individual value would produce an unclear and complex picture, from which it is difficult to draw conclusions. If you zoom in on the Widget timeline, you will see more individual values.

Aggregate: AVG

AVG shows you the average value in the time interval. This is usually used to get a general picture of a situation, or when it is important to know averages.

Aggregate: COUNT

COUNT displays the number of values sent in the time interval. It works on both numeric values and text.

Aggregate: DIFF

DIFF calculates the difference between the first and last values in the time interval. Ideal for when your sensor counts totals, and you want to know the rise or fall of your values.

Aggregate: FIRST

FIRST shows the first value received in the time interval.

Aggregate: LAST

LAST shows the last value received in the time interval.

Aggregate: MAX

MAX shows the largest value in the time interval. Useful when checking something with an upper limit.

Aggregate: MIN

MIN shows the smallest value in the time interval. Useful when checking something with a minimum value.

Aggregate: SUM

SUM calculates the sum of all values received in the time interval.

Alarm

An alarm is a warning you receive, when a certain event occurs. For example, an e-mail when the temperature at your workplace is 25°C or higher, or a Slack message when a vehicle leaves a certain area.

Alarm: Expression

Receive an alert when a sensor's measured value exceeds a preset maximum, or falls below a preset minimum.

Alarm: Geofence

Receive an alert when a device leaves or enters a predetermined area.

Alarm: No Data

Receive an alert when no data is received from a gateway. This usually indicates a malfunction in your device or gateway.

Alert: Positive Hits

When creating an alert, you can choose after how many positive hits the alert should go off. If you want to be alerted immediately, choose 1. If you want this only in the case of a persisting situation, set a higher threshold.

Alarm: Template

If you have multiple sensors taking the same type of measurements, you can create an alert template. This is useful for setting many alerts quickly.

Asset

An asset is a place where data belonging to one of your assets is bundled together, with the goal of displaying it in a dashboard in an organized way.

Asset Type

The asset type determines what information should be collected in an asset. It filters out irrelevant information. It acts as a building plan when creating an asset.

Company

A company is created in the portal when you register. It is the virtual representation of the physical company to which you belong.

Subsidiary

A company subordinate to the parent company.
Users of the subsidiary can make changes in the subsidiary but cannot do so in the parent company.

Computed measurement

This is a calculated value, and allows you as a user to perform additional calculations on measured values, and then display them (for example, a conversion from degrees Celsius to degrees Kelvin).

Dashboard

A dashboard is a visualization of data coming from one or more gateways and the devices connected to them. A dashboard is basically a collection of widgets, such as a graph. You can create multiple dashboards within a project.

Datapoints

Datapoints are the values that a sensor sends to the portal, and are compressed for greater clarity during visualization. You set the level of this compression with Max Datapoints. The higher you set this, the less the compression and the more points will be shown in a Widget.

Datasource

The purpose of a data source is to bring together measured data from sensors, meters, PLC's, ..... that belong to an asset. In the case of the portal, this is the gateway you have selected and devices connected to it.

DeepZoom

DeepZoom enables images with a high resolution, allowing you to zoom in on them without loss of sharpness and with low data usage. It reduces the time required for initial loading by downloading only the area being viewed, while retaining its resolution.

Diagram

A diagram is a graphical representation of a location or schedule. Upload a floor plan or map to the portal and then add the desired objects and sensors, each with an associated icon or image. Clicking on an icon will display the current value of the sensor.

Gateway

A gateway collects data from one or more sensors or measurement devices, and sends it to the portal for further processing.

Geofence

A geofence is a virtual geographic boundary, defined by GPS or RFID technology, that allows the platform to react when a mobile device crosses a boundary. If you have gateways or sensors attached to devices that are not allowed to leave or enter a certain perimeter, it is advisable to set up a geofence on the portal. You will then be alerted when the device leaves or enters this perimeter.

Manual input

It is possible to manually send measurements and values to the Calculus platform. You can also upload complete documents. This data can be integrated into dashboards, reports and current activity. Manually entered data is treated in the same way as data coming from a gateway.

Measurement

A measurement value, such as temperature, position, power, pressure and humidity,...

Measurement Path

A measurement path is the structured way in which measurement data is retrieved from a gateway for processing or visualization. It is structured in the following way: GATEWAY|SLAVE|SENSOR.

Project

You can create a project to collect data related to each other, to be displayed in one or more dashboards. You can think of a project as temporary, or as a permanent facility to which you can add multiple dashboards.

Report

A report is a summary of data uploaded to the portal by your company and its assets. When you create a report, this data is converted to a CSV file for you and offered for download.

Script

You can write your own JavaScript programs, and use the data from one or more gateways as input. This allows you to process a multitude of data and make decisions over longer periods of time. The results of a script are then processed by our system. Scripts are executed on our servers, and thus remain active when you are not logged into the platform.

Script: Memory

You can store the results of your script in memory for reuse in later iterations of your script.

Script: Output

You can output a result of your script to the platform as a measurement value or event. The system will treat it in the same way as input from a gateway.

Script: Alerts

All alerts that are part of the alert system can also be activated from a script.

Sensor

A sensor is a device that takes certain measurements. For example, this can be the C0₂ level, temperature or movement. The readings are collected by a gateway and then sent to the Calculus platform.

Slave

A slave is a device that sends data to the gateway, in most cases we speak of sensors, but these can be other devices as well.

String Value

A string value is a name for normal text.

User

A user of the platform, with a certain set of rights rights.

Value

A value is the measurement value that the sensor sends to the platform through the gateway. It can be numeric, text, or both.

Widget

Widgets are visual representations of measurement data, and are the building blocks of a dashboard. Several types of widgets are available, from simple text blocks to bar charts.

Widget: Action button

If the device linked to your gateway also accepts input, you can have it perform actions by using a widget. Since this is a complicated widget to configure, you can always contact us at help@calculus.group so we can set it up for you. help@calculus.group so that we can prepare them for you.

Widget: Asset Indicators

This widget allows you to display the status of your Homepage's assets in a dashboard, just like in the Homepage.

Widget: Calculus Map

The Calculus map widget shows a map with the locations of your assets. This can come in handy when working with mobile sensors, or to find out the position of offline/defective sensors.

Widget: Chart

A chart is a graphical representation of data, such as a bar chart, line chart, or surface diagram

Widget: Diagram

This widget allows you to integrate one of your charts into your dashboard.

Widget: Dynamic Table

Dynamic tables are characterized by constant change and adjust their content and size when new measurement values are available.

Widget: Meter

The Gauge widget is used to display a gauge value relative to a maximum value, similar to the fuel level gauge in your car.

Widget: Calculus Map

The Calculus Map widget shows a map with the locations of your assets. This can come in handy when working with mobile sensors, or to find out the position of offline/defective sensors.

Widget:Heatmap

A Heatmap is a graphical representation of measured data, where they are represented in a matrix as boxes of a particular color depending on the measured value.

Widget: Recent alerts

This widget shows the most recent alerts sent by your gateways, and the time of each alert.

Widget: Pie chart

A Pie chart is a circular graph representing the relative contribution of different sensors to a total. A wedge of the circle represents the contribution of each sensor, measured in percentages relative to the total.

Widget: Sankey

A Sankey is a visualization of the flow of some measurements and their values to others. It is intended to display flows within a system to show the contributions of inputs to an end point. It can also be used to identify process inefficiencies, or where there are losses.

Widget: Single Block

A Single Block widget is mainly used for measurements where one specific value needs to be displayed, such as the last measured temperature, highest voltage, or the average CO₂ level.
