TMP36+ Galileo

I ordered the TMP36 sensor from sparkfun and connected it to my Aruduino following the circuit

I found Adafruit's tutorial to be a bit easier to follow: https://learn.adafruit.com/tmp36-temperature-sensor/using-a-temp-sensor

and their 3.3 V setting for input voltage definitely works better, i left it running for about an hour to make sure the sensor was working properly

Weatherbox

Physical Computing Midterm Project, SVA Interaction Design MFA Sneha Pai & Matthew Brigante

The Weatherbox is a desk or bedside companion that displays an ambient and abstract light-based representation of the temperature and wind-speed outside your window. Throughout the seasons, it will reflect meaningful shifts in temperature with a specific color of LED light emitted for each incremental range. A reading that is below 35 degrees fahrenheit will be represented by blue lights on both ends of the Weatherbox. For every 15-20 degrees increase in temperature, the Weatherbox will output a warmer color of light. The warmest outdoor temperatures of 80-110 degrees will output a red light. The center panel of the Weatherbox displays the rate of outdoor wind speed with an animated LED array that changes the speed of animation based on the rate of wind passing by your window.

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); } }
