About this item
- A passive-infrared sensor sees people moving across a room.
- Arm the alarm with a code on the membrane keypad; if anyone moves while it's armed the buzzer and LEDs go off until the code is entered again.
- Covers sensors, keypads and a simple state machine.
- The complete kit is the whole parts list as a single item: we collect every part, check it and ship the set together, so nothing is missing when you sit down to build.
- Prefer to buy only some of the parts?
- The project page lists every part with its own price, and you can add just the ones you need.
