#+TITLE: Weather Station
|
|
|
|
The goal of this project is to produce a cheap and reasonably robust
|
|
weather station with low energy usage that can be deployed far from
|
|
any kind of power or network infrastructure.
|
|
|
|
* Design
|
|
** Infrastructure
|
|
*** Data storage
|
|
Removable storage device that can be routinely retrieved and
|
|
swapped out. An SD card seems to be the best choice.
|
|
|
|
*** Power supply
|
|
A pack of rechargable batteries is the simplest solution.
|
|
|
|
** Metrics
|
|
*** Temperature & Humidity
|
|
Off-the-shelf temperature and humidity sensor.
|
|
|
|
*** Insolation
|
|
Off-the-shelf ambient light sensor.
|
|
|
|
*** Pressure
|
|
Off-the-shelf barometer. [[https://uk.rs-online.com/web/p/pressure-sensor-ics/1361511][DPS310]] seems to fit the bill.
|
|
|
|
*** Wind speed
|
|
3D printed cup anemometer using a permanent magnet and a hall
|
|
effect sensor.
|
|
|
|
*** Wind direction
|
|
3D printed wind vane with a permanent magnet on the axis and a
|
|
angular position sensor.
