There are a few issues with this board when connected to the Weather Meter kit:

1) - as noted the values for the wind direction don't match those in the example code. This was the subroutine I ended up using:

char* getWindDirection()
{
  unsigned int adc;
  adc = analogRead(WDIR); //get the current readings from the sensor
  //Serial.println(adc);
  if (adc < 150) return ("SSW");
  if (adc < 300) return ("S");
  if (adc < 400) return ("WSW");
  if (adc < 600) return ("SW");
  if (adc < 900) return ("WNW");
  if (adc < 1100) return ("W");
  if (adc < 1500) return ("ESE");
  if (adc < 1700) return ("SE");
  if (adc < 2250) return ("NNW");
  if (adc < 2350) return ("NW");
  if (adc < 2700) return ("ENE");
  if (adc < 3000) return ("E");
  if (adc < 3200) return ("NNE");
  if (adc < 3400) return ("NE");
  if (adc < 4000) return ("N");

  return ("Error");
}

You'll note there is no SSE - couldn't quite get that to work..

2) Nextly, the UV sensor on the board is acutely sensitive to the angle at which the light is striking it - so if you really want accurate data, you are going to need to rig up some sort of servo motor to follow the sun... Sounded like too much work for me.

3) Still on the UV sensor, just about any enclosure will wildly reduce the UV values. Tried all sorts of things - even cling film took a fair chunk out; although the error from not pointing at the sun (see 2) is much more significant.

4) The rain sensor 'bucket' switch bounces for 2-4 actual clicks per bucket - varies randomly so tricky to calibrate for. A 200ms debounce worked nicely for me:

const int debounceRain= 200;
volatile long lastRainTick=0;
    void rainIRQ()
{
  if (millis() - lastRainTick > debounceRain) rainSum++;
  lastRainTick = millis();
  //Serial.println(rainSum);
}

With the accurate counting of ticks I found the rain sensor calibration was around 0.476

We have almost integrated this into Home Assistant using MQTT server - scope creep currently happily derailing project ;)

Not all sensors are the same...

I've been trying to use the MicroMod Weather Carrier Board with the sensors from a Holman weather station https://www.holmanindustries.com.au/product/aspect-wireless-data-centre-weather-station/

No matter what I did I could not get the anemometer to give a resistance output, either with the MicroMod Weather Carrier Board or directly with a multimeter. The wind speed sensor seemed to work, but didn't seem to be the right resistance for a reed relay.

So I pulled the sensors apart to have a look. From the outside, the anemometer looks identical to the one you sell, but the Holman sensors are now active. Photo of the anemometer internals: https://i.postimg.cc/Qx9thy4p/Holman-weather-station-anemometer.jpg

The 4 wire interface for this version is:

1. not connected

2. Vdd - 3.3v

3. DATA - Wind Direction output

4. anemometer pulse

5. GND

6. not connected

Obviously this sensor array does not work with your board :-(

Update: This sensor array has a serial data stream from the anemometer, protocol currently unknown. https://i.postimg.cc/QMXK8qWh/Holman-weather-station-wind-direction-protocol.jpg

Anyone try this with the XA1110 (Qwiic) GPS? I cannot seem to get it to read GPS data even though it "sees" the module.

Gaaack!

The MicroMod Weather Carrier Board is a PERIPHERAL, not a periphery!

Thanks.

Been waiting for a Weather Board that works with Artemis, thank you!

Can you add to the Hookup Guide details about using an analog capacitive soil moisture sensor (such as DFRobot's Gravity Soil Moisture Probe dfrobot.com/product-2054.html my goto soil sensor these days) via the latch terminals G0/Bus0 and A0?

Better yet for V2 of the Weather Board is adding a jumper that bypasses the micromod connector to provide power directly from the voltage regulator to the latch terminal instead of G0/Bus0.
