Quick Answer

Why is my door opening randomly?

This is often 'ghosting' caused by radar interference or sensor drift. In Clerkenwell, we see this frequently with older analog sensors. We upgrade these to digital units that filter out environmental noise.

Component Analysis

Brushless DC Motor: We test internal resistance to detect winding faults common in high-cycle Clerkenwell venues.

Sensor Fusion: In Clerkenwell, we recalibrate Microwave Radar for motion and Active Infrared for presence to prevent ghosting.
