Xiaomi Door sensor - Door lock sensor

prusaprinters

<p>So this is really simple.</p><p>I use a Xiaomi door sensor in my door lock, so when the door is locked the metal arm goes down and triggers the closed state of the sensor ( use some magnets to trigger this ) so this way i know when the door is locked or unlocked.</p><p>The “box” is just a extension to make the sensor come in the right height to get triggered</p>
