capacitive-soil-moisture-sensor's Issues

Make sensor including case more compact by using single AAA + voltage booster

The sensor including the case is too bulky. The ability to use 2x AAA batteries is nice but it would be way more compact with using a single AAA battery. For this to work there has to be a voltage booster. This will inevitably lead to more components but voltage boosters usually have no more than 3-4 additional SMD components.

EDIT: However, component prices have to be considered as low power voltage boosters are currently quite expensive due to shortages.

Distance test

Hi,
When you use your enclosure box, how much range can you get on the open field with line of sight?

Make creation of production files scriptable

Production files are currently generated by hand. This is error prone and not fully reproducible.
A nice solution for this is to intregrate KiBot together with a Makefile. This would make it much easier to generate a suite of production files, including the assembly files which are currently not available.
Going further down the road this should also be implemented as a GitHub action to automatically generate all production files for new releases.

Add tips on waterproofing to README

In the README there should be some tips on making the PCB water resistant.

Create OpenSCAD file for the case

In order to be able to version control the case and enable other contributors to work on it there should be an OpenSCAD version of it.

Additionally the print time and material consumption of the case should be reduced.

Improve the workflow of calibrating the sensor values

Currently it is quite cumbersome to calibrate the raw sensor values as one has to upload the sketch in CALIBRATION_MODE first, note the values in air and water, update the sketch and reupload it to the sensor. When trying to deploy a lot of these sensors this takes a lot of time. A nicer way would be to include a second button and an LED which could drive a small "calibration interface".

without ATSHA204A

hi, can i use it without this ATSHA204A?
