Harry Potter: "What's that?"
Professor Moody: "Secrecy Sensor. Vibrates when it detects concealment and lies... no use here, of course, too much interference—students in every direction lying about why they haven't done their homework."
— The fake Alastor Moody explaining his Secrecy Sensor to Harry Potter.[src]

A Secrecy Sensor is a type of Dark Detector. It is shaped like an aerial, but it is gold in colour and very squiggly. It vibrates when it detects concealment and lies.

History

1994-1995

The Fake Alastor Moody had one in his office during the 1994–1995 school year at Hogwarts School of Witchcraft and Wizardry. However, it was no use to him at the school because it was constantly humming, as (supposedly) students were always nearby telling lies about why they had not completed their homework assignments. However, it is more likely the result of him masquerading as another.

1995-1996

When Harry entered the Room of Requirement, he also discovered several secrecy sensors among other Dark Detectors.

1996-1997

During the 1996–1997 school year at Hogwarts, as part of the school's increased security measures, caretaker Argus Filch scanned all students who entered or left the school with a secrecy sensor.

Possible uses

When Harry first visits the Ministry of Magic in August 1995 the wizard at the security desk checks him over a Secrecy Sensor before letting him enter further into the Ministry.[1]

Behind the scenes

  • Secrecy Sensors appear vastly different in the Nintendo DS version of Harry Potter and the Deathly Hallows: Part 1. Here, they are areas of light that move along the ground in set patterns, appearing similar in appearance to spotlights. When Harry steps into one, it causes a number of wizards to Apparate to his location and attack. Interestingly, Ron, who is controlled by the game, does not activate the Secrecy Sensors should he step into one. This may be so the player is not attacked due to actions outside his control, or merely an error in programming.

Notes and references

  1. The physical description of a Secrecy Sensor is quite alike that of a Probity Probe, as such we are not sure what was used there.
