    A DIY weather display with dedicated outdoor sensor station

    Weather stations are popular projects in the maker community because they’re useful and usually quite affordable to construct. But most that we see are really weather information displays that gather data through the internet from stations in the region. That data is fairly accurate, but there can be minor differences due to microclimate zones. So, Wilson Malone decided to build his own system with a dedicated outdoor sensor station.

    Malone’s system consists of two units: the indoor display and the outdoor sensor station. The latter receives its power from a solar panel and battery backup, so Malone can place it anywhere that gets good sunlight within wireless range of his home. It has a sensor to detect wind speed, another sensor to detect wind direction, and a PHT (pressure, humidity, temperature) combination sensor. An Arduino UNO Rev3 board reads those sensors and then transmits the data using a 915MHz radio transceiver.

    Inside the home, the indoor display unit receives that data with a radio transceiver of its own. An Arduino UNO R4 WiFi parses that and then shows each value on a four-digit seven-segment display. The Arduino will also publish the values to a self-hosted webpage every eight seconds. Any users on the same local network can visit that page to view the current information.

    Now Malone has a hyperlocal weather station that gives him accurate information about the weather in his exact location.

    Going outside to see the weather is time consuming and merely looking at a phone gets boring, which is what inspired YouTuber Mikey Makes to build a fun weather-telling device that displays the current conditions in a new format. Owing to his love of the old BBC weather symbols, which were placed on physical stickers rather than a computer screen, Mikey Makes wanted to replicate them and physically swap out various components in a mechanical fashion.

    At the very front is a large gray cloud that is permanently fixed in place. If the conditions outside become cloudy, rainy, or snowy, small symbols for each state are rotated underneath the cloud using a stepper motor in conjunction with a DC gear motor. The symbols for partly cloudy and full sun were tougher to integrate since they are either behind the cloud or completely cover it. For partial sun, a series of disks rotate behind the cloud to slowly pull up the rays of sunshine that emanate outwards. Otherwise, full sun causes a large sun symbol to move across the front of the cloud and block it entirely.

    Controlling all of these components is a MKR WiFi 1010, which pulls real-time weather data from the openweathermap API. Then depending on the desired movements, it sends signals to an A4988 stepper motor driver or an H-bridge module for the DC motors. 

    To see more about how this project works and its intricate mechanical design, you can watch Mikey Makes’ demonstration video below!

    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.

  • Check the weather on this Arduino-controlled split-flap display

    Check the weather on this Arduino-controlled split-flap display

    Arduino Team — August 9th, 2018

    Split-flap displays show information using characters changed by an electric motor. While they’ve largely been replaced by more modern means, hobbyists like “gabbapeople” have been keeping this this technique alive, in this case as a four-character IoT weather display.

    The device is built using laser-cut plexiglass, and uses four individual servos to actuate the character flaps. Control is accomplished using an Arduino Mega programmed in the XOD visual programming environment, along with the requisite driver modules. Weather data is pulled from the AccuWeather API. 

    You can see it flapping away in the video below, displaying the weather in abbreviations such as “ICLO” for intermittent clouds, as well as the temperature in degrees Celsius.
