Door Alarm Project Explanation at Ollie Dunlap blog

Door Alarm Project Explanation. The circuit is built around hall sensor a1301 (ic1), timer ne555 (ic2), a powerful magnet and a few discrete components. When the door is opened, the magnet moves away from the sensor, generating a controlling signal to sound the alarm. This tutorial will show you how to create a simple door security alarm circuit that will give you peace of mind and keep your home safe and secure. And the alarm remains on as long as the door is kept open. A door opening alarm circuit is an indicator or a security alert device which activates while opening the device attached door. Door opening alarm circuit diagram. This instructable will guide the reader through the process of making an arduino controlled door alarm. This circuit is easy to build and can be customized to suit your specific needs. A homemade alarm might be just the thing you need to keep nosy siblings from poking. In this magnetic door alarm circuit, we have used a 555 timer ic in astable mode to generate a tone as an alarm; This device will play a song when the designated microswitch is triggered.
