1 Maplin weather station part numbers: Anemometer 2.49 part number :- N25FR Wind direction sensor 9.99:-N96FY You can build this onto a little strip board for easy connection :) Ardunio with Ethernet Shield You can see a live version of this weather station running at : debdalelodge.ddns.net Ethernet connected weather station - By Mike Gaylor (

2 Arduino Code:- Please note this code is not perfect and does have a few bugs but it works, feel free to make it better and send me a copy :) /* station with Ethernet connectivity A simple web server weather station by Mike Gaylor using the Arduino Uno and Ethernet shield - Circuit: * Ethernet shield attached to pins 10, 11, 12, 13 * Analog inputs: Connect maplin wind direction sensor to A0 connect Maplin anemometer to D5 See Circuit Diagram. */ // Must make sure these are in the Arduino Libary! #include <SPI.h> #include <Ethernet.h> #include <MsTimer2.h> // Global Variables. //hardwarecounterpin = 5; const int sampleperiod = 2000; unsigned int count = 0; float numberofcounts = 0; int clock = 0; long starttime = 0; float peekwind = 0; float gust = 0; int sensorreading = 0; int peakcounter = 0; //Averaging stuff ************************************************** const int numreadings = 30; int readings[numreadings]; // the readings from the analog input int readindex = 0; // the index of the current reading int total = 0; // the running total int average = 0; // the average //***************************************************************** Arduino Code 1
