    Weather stations are very popular projects for people new to Arduino. They’re complex eno­­­ugh to help a person learn new skills, but they’re simple enough to be approachable. However, that popularity has led to something of an arms race, with many makers attempting to design the most impressive weather stations on the internet. If you want to go back to the basics to dip your toes into the water, Mirko Pavleski explains how to build a classic weather station that prioritizes the essentials.

    Inspired by older devices that displayed information like temperature, barometric pressure, and humidity on analog gauges, Pavleski chose a design with three screens in a vertical stack. Each screen can display whatever data the user can access through a sensor. In this case, his station utilizes the popular BME280 module that monitors the same three parameters as the vintage inspiration: temperature, pressure, and humidity. 

    This weather station shows each reading on a small two-tone OLED screen. Those screens have yellow pixels on the top and blue pixels on the bottom, which is handy for distinguishing the title from the data without the expense or complexity of a full-color screen.

    An Arduino Nano board reads the data from the BME280 sensor and writes to the displays. But those displays and the BME280 all connect through I2C. To interface with all of them through the single pair of SCL/SDA pins, Pavleski included a TCA9548a multiplexer module.

    Those components all mount in a minimalist enclosure made from foam board. And while we certainly enjoy complex weather stations, we appreciate the simplicity and approachability of this design.

    Constructing your very own IoT weather monitoring station can be a complicated ordeal, as getting values from the embedded device to some kind of web server in a secure manner takes a lot of effort and time to complete. For his system, Clem Mayer from element14 Presents was able to use a MKR WiFi 1010 that sends relevant weather information at a set interval, which can then be viewed from anywhere in the world with an Internet connection.

    Aside from the Arduino as the main control board, Mayer went with a DHT11 temperature and humidity sensor for collecting weather data and a LiPo battery cell that lets this device sit outside for extended periods of time. In the future, Mayer speculated that he might add light or gas sensors for even more in-depth readings. All of the electronics were placed into a watertight enclosure, which has a clear acrylic top for viewing the status RGB LED.

    The Arduino Cloud service was used to configure the MKR WiFi 1010, set up several cloud variables, and create a virtual dashboard for keeping tabs on both current and historical readings. After making the processor sleep for eight seconds to conserve battery power, a reading is taken from the onboard sensor and written to the cloud where it can then be seen in the dashboard.

    Stream weather conditions to the cloud!

    Arduino Team — November 26th, 2018

    Weather reports on the news, your computer, or smartphone are very good—something that people 100 years ago could only dream of—but what if you want to know the exact weather in a fixed location from anywhere in the world? One solution would be Jakub Nagy’s excellent cloud-connected station.

    It uses an Arduino Uno to collect data from temperature, humidity, pressure, and UV index sensors, along with a Nano to read a rain gauge. The data, with images from a webcam, are passed along to a service called Weathercloud, where this report out of the Slovak Republic can be viewed remotely. 

    If you’d like to assemble a similar device to measure conditions in your area, instructions are available in his write-up, including a parts list that will run around $130.

    A 3D-printed personal weather station

    Arduino Team — April 9th, 2018

    If you need to know the forecast, generally you can look outside, listen to a weather report, or take advantage of the wide range of online services available. For something local to your dwelling place, however, this 3D-printed weather measurement device gives a great way to see what’s going on.

    The system features a 3D-printed rain gauge, anemometer, and weather vane, along with a barometer and temperature sensor. Information from these sensors is piped to an Arduino Uno and displayed on a 4×20 character LCD.

    While meant as a demonstration for an arts/science exhibition and would need to be calibrated for real world use, it is a perfect starting point if you’d like to build your own personal station!

    The thrust bearings should be a tight fit and not require glue. The 5mm brass tube for the axles though will benefit from some cyanoacrylate on the ABS to hold them in place. Rough the tube up a bit with sandpaper or a file to help adhesion. The temperature and barometric pressure does not need calibrating. However rainfall (it is fairly close) and wind speed will need calibration. As long as the magnet in the wind direction sensor is close enough to trigger two adjacent reed switches when half way between the two reeds, it will allow 8 reed switches to reliably indicate 16 directions.

    The reed switches in the direction indicator are vertical and are not trimmed, just the top end curled over to allow easy soldering to the common earth wire ring. Extra spacing maybe required, eg a small ring of heat shrink tubing to keep the moving parts of the anemometer and wind speed separated and seated on the bearings in the stationary base. This was too fine to print.

    All the magnets N-S poles should be aligned along the line of the reed switch. The magnet lines of force between N-S have the best switching effect, not one of the poles, N or S, on its own. This also helps eliminate bounce, or multiple triggering.

    More details on the project can be found on Thingiverse.
