Greenhouse door controller box

thingiverse

Automatic Greenhouse Door Opener Goal Opening the greenhouse door automatically when the room gets too hot is my goal. I have set it to open at 24 degrees C and reach maximum position when there are 32 degrees C. Used Hardware In box Arduino Nano Clone - main "brain" of the project, powering everything. 5110 LCD - info display for users. DS18B20 - temperature sensor for accurate readings. SRD-05VDC-SL-C - 2 relays for controlling door movement. LEDs x 6 - indicators for status and operation. Resistors - voltage regulation. Capacitors - 3x, filtering unwanted signals. Level Shifter 5V->3.3V - safely switching between voltage levels. 7805LM - converting 12v to 5v power source. 10A Fuse and Fuse PCB Mounts - protection against electrical surges. PCB Screw Terminals - easy connection for electronics. On door Car Side Window Lifting Motor and Mechanism - powerful motor for opening the door. Magnet and PS-3150 Reed Switch - sensing home position of the door. Switch - manual override for door "homing". Bolts, Nuts, Threaded Bar - structural support for the mechanism. Software I wrote code for Arduino to control the door's movement. The Arduino checks if the home switch is pressed. When it's not pressed, the Arduino tries to close the door. Once closed, it measures temperature and calculates position based on temperature readings. PCB I designed the PCB with Inkscape because I didn't have time to learn other CAD software. The design was cut out using a vinyl cutter and etched for circuit board production. After that, the PCB was drilled for component installation. Electronics Box I designed it in TinkerCAD and printed it out with Ender 3 3D printer for easy assembly.
