Water sensor1: common questions

What microcontroller does the Water sensor1 use?

The Water sensor1 is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.

How big is the Water sensor1 PCB?

The Water sensor1 measures 48.3 × 58.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Water sensor1?

11 components, from 10 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Water sensor1 design files?

From the ARTS-Laboratory/In-Situ-Water-Quality-Sensor repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Water sensor1 design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which ARTS-Laboratory chose for the repository.

Can I test firmware for the Water sensor1 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.
