IoT power consumption

In industrial IT, organizations must accurately compute the power consumption of devices to optimize energy use, reduce costs, and ensure sustainable operations. They need specialized database features to manage the vast and dynamic data generated by these devices and then offer real-time analytics for predictive modeling to maintain efficient energy management and operational continuity. In this example, you will explore how to build an aggregation pipeline to calculate the power consumption of devices.

Note

For this example, you require MongoDB version 5.0 or above. This is because you'll be using time-series collections, the $setWindowFields stage, and the $integral operator introduced in version 5.0.

Scenario

You are monitoring various air-conditioning units running in two buildings on an industrial campus. Every 30 minutes, a device in each unit sends the unit's current power consumption reading back to base, which is persisted in a...
