Mois sensor node
Tip
You might want to read this document on our documentation space, all inline links will be working there.
Introduction
This firmware powers the Mois Box, based on the Arduino Yún Shield-compatible Dragino Yun Shield v2.4. Telemetry data is transmitted to a custom PHP receiver program over HTTP using the Yún HTTP Client from the Bridge Library for Yún devices. It is also stored locally on a SD card. The most recent firmware version is always available at node-yun-http.ino.

Setup
Clone git repository
# Get hold of the source code repository including all dependencies
git clone https://github.com/hiveeyes/arduino
# Select this firmware
cd node-yun-http
Configure firmware
Have a look at the source code node-yun-http.ino and adapt feature flags and setting variables according to your environment.
Configure load cell calibration settings:
// Use sketches "scale-adjust-hx711.ino" or "scale-adjust-ads1231.ino" for calibration
// The raw sensor value for "0 kg"
const long loadCellZeroOffset = 38623;
// The raw sensor value for a 1 kg weight load
const long loadCellKgDivider = 11026;
Tip
Read about Firmwares for load cell adjustment to determine those values.
Build
The build system is based on PlatformIO, which will install toolchains and build your customized firmware without efforts. All you need is a Python installation.
# Build firmware
make build
Note
If you need to build for different targets, or if you want to modernize your dependencies,
you may want to adjust the platformio.ini file, to match your needs.
In order to make changes to the firmware, edit the node-yun-http.ino file, and
invoke make build to build it again.
Upload to MCU
