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