Consumption table

In the following table, the consumption shown by the board when active is detailed, the minimum consumption (constant, fixed by the permanently active components, such as the adaptation electronics) and the individual consumptions of each of the sensors connected alone to the board (the total consumption of the board with a determined sensor will be calculated as the sum of the constant minimum consumption of the board plus the minimum consumption of the group to whom the sensor belongs plus the consumption of the sensor).
Remember that the board's power can be completely disconnected, reducing the consumption to zero, powering off all the sensors.
