Weather Board

Weather Board[/caption] The Weather Board is a weather station controller board designed to interface to Arduino and Raspberry Pi computers.  It is an interface board developed by SwitchDoc Labs to allow the user to easily build a fully functioned Weather Station while allowing customization of functions. The Weather Board is derived from Project Curacao and the WeatherPiArduino.  Generation 1 of this board was deployed and tested in Curacao before Generation 2 was released to production.  The full WeatherPiArduino article was published in Raspberry Pi Geek magazine in September, 2014 and a follow up article has been published in April, 2015 (including the new lightning detector).  The Weather Board comes with a SwitchDoc Labs DS3231/EEPROM board. Combine the Weather Board with a SunAir or SunAirPlus board to create a solar powered weather station.

Want to build a control panel for the Weather Board?  Look at this post and the picture below:

[caption id="attachment_703" align="aligncenter" width="300"]WeatherPiArduino RasPiConnect Weather Board RasPiConnect Control Panel[/caption] [caption id="attachment_697" align="alignleft" width="225"]SparkFun SwitchDoc Labs WeatherRack Sensors[/caption] The SDL_Weather_80422 class library is designed to provide all the functions of the SwitchDoc WeatherRack, ArgentData Weather Sensors,  SparkFun Weather Meters SEN-08942 in one C++ class. The library is easy to use and hides the complexity of the interface to the sensors.  The C++ class has two Interrupt Service Routines (ISR), one each for the anemometer and the rain bucket.  The wind vane is connected to an Analog to Digital Converter (ADC) input pin on the Arduino.  Note that the C++ class is designed to be a singleton, in other words, you only can interface one sensor package without some additional work (mostly involving Interrupts).  The article in Raspberry Pi Geek magazine discusses this in detail. There are two main modes for the class.

SDL_MODE_SAMPLE

SDL_MODE_SAMPLE mode means return immediately after asking for the wind speed. The wind speed is averaged at sampleTime or since you last asked, whichever is longer. If the sample time has not passed since the last call, the class returns the last calculated wind speed. That means that you will never see changes faster than the specified sample time. This allows you to not wait for the wind speed, you can just grab the last valid reading.

SDL_MODE_DELAY

SDL_MODE_DELAY mode means to wait for the set sample time to expire and return the average wind speed at the expiration. You would use this if you want to make sure you have the latest value and your program architecture allows you to pause for the sample time before continuing. Which mode you use depends on the specific software architecture of your Arduino application. Typically, I use SDL_MODE_SAMPLE because I can tolerate not having a current value of wind speed. The example code for the SDL_Weather_80422 library is shown below:

// initialize SDL_Weather_80422 library
SDL_Weather_80422 weatherStation(pinAnem, pinRain, intAnem, intRain, A0, SDL_MODE_INTERNAL_AD);


uint8_t i;


float currentWindSpeed;
float currentWindGust;
float totalRain;
void setup()
{ 
Serial.begin(57600); 

Serial.println("-----------");
Serial.println("WeatherPiArduino SDL_Weather_80422 Class Test");
Serial.println("Version 1.0");
Serial.println("-----------");


weatherStation.setWindMode(SDL_MODE_SAMPLE, 5.0);
//weatherStation.setWindMode(SDL_MODE_DELAY, 5.0);
totalRain = 0.0;
}


void loop()
{
Serial.println("----------------");

currentWindSpeed = weatherStation.current_wind_speed()/1.6;
currentWindGust = weatherStation.get_wind_gust()/1.6;
totalRain = totalRain + weatherStation.get_current_rain_total()/25.4;
Serial.print("rain_total=");
Serial.print(totalRain);
Serial.print(""" wind_speed=");
Serial.print(currentWindSpeed);
Serial.print("MPH wind_gust=");
Serial.print(currentWindGust);
Serial.print("MPH wind_direction=");
Serial.println(weatherStation.current_wind_direction());


delay(1000);


}

When you run this, you should get a result similar to this:

  1. Just the job

    Posted by Ian on Dec 19th 2016

    Experimenting with a DIY remote automatic weather station, this board has saved a lot of head scratching, allowing the weather sensors to connect directly to the Raspberry Pi.

    If you are ordering this from the UK take advantage of the higher rate delivery options if you want to avoid the ridiculous Royal Mail handling charge and don't forget to allow for VAT.
