Monitor Detector Teardown

The thing I teardown is a monitor detector. Because I bought it on second hand, first I need to figure out how does it work.

It has RF wireless signal detection, magnetic field detection and hidden camera detection. When the signal goes high, the screen will light up and it will vibrate. Also there are buttons and knob for you to adjust the function.

The teardown part is shorter than I thought, and here are the parts and the time-lapse video.

Parts:

  1. knob for on and off and control
  2. nut that fixed the knob on the outside
  3. filter lens in the middle
  4. double-sided tape to fixed the battery
  5. GS probe for information transition
  6. lithium battery
  7. the part connect to the MC1
  8. font shell
  9. back shell
  10. two circuit boards, the upper one is DSK18D27, the lower one is DSK19A01 (I googled both of the name of the data sheet, but couldn’t find the exact one, and the searching result is very limited, maybe someone can teach me a different way to find the datasheet so that I can find out what the No.7 function)
