About the Humidifier PCB

Humidifier is an open source AVR/Arduino PCB design by priyanshu643, published on GitHub. It is a 2-layer board measuring 127.8 × 66.8 mm, with 19 components from 12 distinct parts.

Its main chip is the ATmega328P-A, from the AVR/Arduino family. Other key parts include the LM7805_TO220. By type, the board carries 5 resistors, 4 connectors, 3 capacitors, 2 ICs, 2 crystals and 1 transistor.

It belongs with the sensors designs in this gallery.

From the project

Welcome to the repository for my DIY Humidifier project! This project aims to create a functional and efficient humidifier, featuring a custom-designed Printed Circuit Board (PCB) to integrate all components neatly.

Humidifier: common questions

What microcontroller does the Humidifier use?

The Humidifier is built around the ATmega328P-A, from the AVR/Arduino family.

How big is the Humidifier PCB?

The Humidifier measures 127.8 × 66.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Humidifier?

19 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the Humidifier design files?

From the priyanshu643/Humidifier repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Humidifier design in my own project?

The repository has no license, so all rights stay with priyanshu643. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Humidifier without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
