Water Quality Sensor: common questions
What microcontroller does the Water Quality Sensor use?
The Water Quality Sensor is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.
How big is the Water Quality Sensor PCB?
The Water Quality Sensor measures 44 × 58.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Water Quality Sensor?
8 components, from 8 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 Quality Sensor 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 Quality Sensor 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 Quality Sensor 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.
