Sensor placement mattered more than sensor type
Groups that repositioned their sensor based on their evidence found more meaningful variation in their readings than groups that changed sensors.
Evidence pattern
Across investigations, teams who mapped readings in multiple positions often found a location where the signal changed clearly, even when using the same sensor type.
What it might mean: The investigation should tell you where to put a sensor. Changing hardware doesn’t help if the placement can’t detect the variation you care about.

Before changing your sensor, map readings at three different positions to find where variation is highest.
