This door-window sensor magnetic reed switch for security/alarm systems is great for DIY alarm systems and Arduino-based security systems.
This device is like the common sensors used by professional security systems to detect window and door intrusions.
It uses a magnetic reed switch in one section and a magnet in the other, so when the two are separated, the state of the switch is changed.
