Your project simulation just ended! You are now on the "Results" page.
We will explain the "Results" page using a specific project, "Sens'it V3". Sens'it is a test device produced by the communication technology provider Sigfox. We reproduced its hardware and software in Wisebatt.
You can access this public project but not edit it. If you want to change its components, parameters and states, simply "Fork" this project to make it your own. More on Fork here.
On the top left you will find the battery life estimation of your device. It represents the time that your device will last from a fully charged battery until it stops working.
When does a device stop working? 2 reasons here :
The battery is depleted - which means that the battery ran out of power.
The device achieved its “highest cut-off voltage” - which means that the device stops working once the battery supply voltage goes beyond the tolerated supply voltage range.
From Device Overview to Component Focus
There are two possible ways to visualize results :
Device overview (ALL). Visualisation of results considering the entire device.
Component focus. Focus on results considering specific components.
To focus on a specific component, click on its name.
The consumption distribution graph displays how much of the overall battery consumption is consumed by each category of component. Each category of component is represented by a slice of the graph.
When you focus on a component, Wisebatt displays a breakdown of the consumption of this component. It displays how much power this component is consuming in its category.
Time vs Energy Distribution
Click on a component to view its Time vs Energy Distribution graph. Here we selected the MCU STM32F042X.
When an MCU processes tasks, it spends some specific time doing these tasks.
The duration of this time does not necessarily reflect how the power is spent in each of these tasks (e.g. the MCU can spend 90% of the time doing the calculation and it will represents only 10% of consumed power). This graph allows in-depth comparison of time spent in each state vs the power consumed by each state.
In the legend above, all the states that your component can handle are displayed. We decided to keep them all in this graph for your information. In this case, our component only spends time in "RUN" (black) and "SLEEP" (blue) modes as you can view in the graph.
Voltage and Current
These graphs display how the battery is used from the beginning until the device stops working. It is a standard representation in the electronics industry which is helpful to see if there was a mistake or an error in the design (e.g. overconsumption of one of the components or a voltage that should not exist).
These graphs might sometimes not appear instantly. Just wait for a few seconds for them to display.
Use the handles below each graph to zoom in / zoom out.
These graphs can be accessed at the scale of the entire device or for each component. View section "From Device Overview to Component Focus" above to learn more.
You can also access the raw data of each graph by clicking the "Data View" button.
Finally, you can export this page as a PDF by clicking the button "Export as PDF".
