RFID Shed Door Lock

prusaprinters

<p>A simple RFID locking system for my shed but without putting anything outside so I didn't haft to make anything weather-proof. Luckily the RFID range easily went through the window of my shed so I designed a case to hold it in the corner of the window and then a case to hold the raspberry pi and relay switch.</p> <p>I use a solar power system in my shed and I already have a lot of LED's on it and found the Lock would not engage whilst the lights were on so I implemented a button (link below) that would tell the Pi to break the circuit of the light with the relay and in turn connect the circuit for the lock.</p> <p>I decided to add the 5v fan to the control box as my shed is insulated and gets quite hot so I didn't want the Pi to overheat.</p> <p>The case for the RFID reader worked really well so I might create some variations of it for mounting on a wall when I get time.</p> <p> <figure class="media"> <oembed url="https://www.youtube.com/watch?v=N5Ar4FzGX-U"></oembed> </figure> </p> <p>Parts Used:</p> <p>-RC522 RFID reader<br/> -Green LED<br/> -Red LED<br/> -2 x 330Ω resistors<br/> -1-Relay 5V KY-019 Module<br/> -Raspberry Pi Zero W<br/> -5v fan (optional)<br/> -DC12V Electronic Door Lock B3H3<br/> -Tactile Switch<br/> -4 x M3 10mm Bolts and Nuts</p> <p>Button Holder: <a href="https://www.thingiverse.com/thing:2235586">https://www.thingiverse.com/thing:2235586</a></p> <h3>Print instructions</h3><p>All printed in PETG to better hold up to the heat in my shed.
