Hold your packages secure with Clem Mayer’s safe parcel pickup field

As part of his enterprise, element14 Presents’ Clem Mayer sells bodily items on-line and has individuals retrieve them close to his home. However for the occasions he’s not in a position to be dwelling, Mayer was impressed by his publish workplace’s pickup lockboxes to create his personal model that may very well be accessed with only a code at any time.

As a result of this parcel container could be outdoors and uncovered to the weather, Mayer went with a sturdy electronics cupboard that’s IP66 rated and made totally from steel. Initially, he was pondering of a system that might require customers to scan a QR code on the field, go to a web site, after which enter the code to achieve entry. Nevertheless, the advanced nature and community connectivity led him in direction of a a lot easier answer instead- simply enter the digits on a bodily keypad. This fashion, a single code may very well be set within the Arduino Leonardo’s EEPROM after which in contrast every time a complete of six digits are chosen.

The PCB Clem designed accommodates a header for the Arduino, a 4×4 grid of tactile pushbutton switches, six LEDs on the high to sign which digit is energetic, and a relay for unlocking the field. The mechanism itself is an off-the-shelf latch housing a solenoid that unlocks at any time when energy is utilized from the 12V energy supply.
