#tmp36

Method

For the wind aspect of the Weatherbox, we used a wind sensor (from Modern Device). 

For the temperature aspect, we used a TMP 36 temperature sensor (from Sparkfun).

Arduino code

For temperature sensor:

int redPin = 11; int greenPin = 10; int bluePin = 9; const int tmp= A0; void setup() { pinMode(bluePin, OUTPUT); pinMode(greenPin, OUTPUT); pinMode(redPin, OUTPUT); Serial.begin(9600); } void loop() { int sensorValue = analogRead(tmp); float mVoltage = sensorValue * 5000.0/1024.0; float tmpC = (mVoltage - 500) / 10.0; Serial.print(tmpC); Serial.println(" degrees C"); delay (1000); if((tmpC <= -1 ) && (tmpC >= -17)) { setColor(0, 0, 255); } // blue else { setColor(0, 0, 0);} if ((tmpC <= 7 ) && (tmpC >= -0)) { setColor(0, 255, 255); } // aqua else {setColor(0, 0, 0);} if ((tmpC <= 22 ) && (tmpC >= 8)) { setColor(0, 255, 0);} // green else {setColor(0, 0, 0);} if ((tmpC <= 27 ) && (tmpC >= 23)) {setColor(255, 255, 0); } // yellow else {setColor(0, 0, 0);} if ((tmpC <= 40 ) && (tmpC >= 28)) {setColor(255, 0, 0); } // red else {setColor(0, 0, 0);} } void setColor(int red, int green, int blue) { analogWrite(redPin, red); analogWrite(greenPin, green); analogWrite(bluePin, blue); }

For wind sensor:

// // Written for the LoL Shield, designed by Jimmie Rodgers: // http://jimmieprodgers.com/kits/lolshield/ // Adapted from Noisy by Jacob Joaquin <[email protected]> 10/3/2012 //wind sensor parts int windmin; int windmax; //lolshield #include "Charliplexing.h" void setup() { //lolshield setup LedSign::Init(); //wind sensor setup Serial.begin(9600); windmin = analogRead(A0); // calibrate wind sensor on analog pin A0 windmax = windmin+400; //this is where the range is declared } void loop() { int windSensor = analogRead(A0); // read wind sensor value // if(windSensor<windmin) windSensor=windmin; // compress ends of scale to avoid going out of range if(windSensor>windmax) windSensor=windmax; // int windoutput = map(windSensor, windmin,windmax,0,100); //remap wind value to length of array Serial.println(windoutput); delay(150); if ((windoutput <= 10) && (windoutput >= 0 )) { for(uint8_t y = 0; y < 9; y++) { for(uint8_t x = 0; x < 14; x++) { LedSign::Set(x, y, random(2)); } } delay(2000); } else if ((windoutput <= 20) && (windoutput > 10 )) { for(uint8_t y = 0; y < 9; y++) { for(uint8_t x = 0; x < 14; x++) { LedSign::Set(x, y, random(2)); } } delay(1500); } else if ((windoutput <= 30) && (windoutput > 20 )) { for(uint8_t y = 0; y < 9; y++) { for(uint8_t x = 0; x < 14; x++) { LedSign::Set(x, y, random(2)); } } delay(1000); } else if ((windoutput <= 40) && (windoutput > 30 )) { for(uint8_t y = 0; y < 9; y++) { for(uint8_t x = 0; x < 14; x++) { LedSign::Set(x, y, random(2)); } } delay(750); } else if ((windoutput <= 50) && (windoutput > 40 )) { for(uint8_t y = 0; y < 9; y++) { for(uint8_t x = 0; x < 14; x++) { LedSign::Set(x, y, random(2)); } } delay(500); } else if ((windoutput <= 60) && (windoutput > 50 )) { for(uint8_t y = 0; y < 9; y++) { for(uint8_t x = 0; x < 14; x++) { LedSign::Set(x, y, random(2)); } } delay(300); } }
