4 Summary

In summary, the door and window sensor evaluation platform can be leveraged to evaluate and compare TI's DRV5032 Hall-effect switch, the 3D linear output Hall-effect sensor, and a radial glass tube Reed switch simultaneously to show positives and negatives of each. The TMAG5273 has a larger detection range for both magnets used in the testing and offers greater detection modes of operation while greatly reducing susceptibility to tampering attempts that can otherwise go undetected with a typical Reed switch door and window sensor. Due to the low power requirements of door and window sensors, a combination design of an ultra-low power DRV5032 as a first-pass detection switch, along with the TMAG5273 for secondary event detection and tamper detection, provides a much more robust answer for door and window sensor applications than the typical Reed switch design. More advanced door and window sensors can also leverage accelerometer data for brute force break-in attempt detection as well as provide sensor mounting position indication which can be leveraged to indicate which direction a magnetic field needs to approach during normal operation versus during a tampering attempt.
