Project Planning, Temp & Humidity Online

-

hi everyone, i'm new arduino , first post forums!

i'm planning on building small unit report temperature , humidity of remote location online.

my plan use uno , temp/humid sensor testing , move gemma wifi or bluetooth final build , use openhab reporting interface.

i know won't built overnight , expect learn lot trying avoid pitfalls of buying stuff won't work. i'm asking guidance. there anyway put temp sensor on uno , report out of usb? i'd love guidance on components need pull off. thanks!

so i'm asking guidance. there anyway put temp sensor on uno , report out of usb?
yes. trivially easy, actually. code temperature depend on temperature sensor choose. code data out serial port serial.print(thetemperature);.

also i'd love guidance on components need pull off.
what level of granularity need temperature? cold hell, nippy, cool, warm, , sweating fool head off require different equipment nearest 0.001 degree f.

how far need send data wirelessly? 10 feet? bluetooth perfect. 10 miles? neither bluetooth or wifi appropriate.

i'm struggling dht11 sensor work on arduino. code compiles without problems in serial monitor output keep on getting " read sensor: time out error" i've tried multiple libraries, adafruit etc still none of them worked. set serial monitor same speed (115200) didn't fix problem.  i'm using:  mega2560  dht11 temp+hum sensor windows10 x64 arduino 1.6.9 library dht11.h v0.4.1 source:  http://playground.arduino.cc/main/dht11lib wiring : blue = gnd yellow = 2 red = 5v (also see picture)  my code:    code: [select] #include <dht11.h> // //   file:  dht11_test1.pde // purpose: dht11 library test sketch arduino // //celsius fahrenheit conversion double fahrenheit(double celsius) {   return 1.8 * celsius + 32; } // fast integer version rounding //int celcius2fahrenheit(int celcius) //{ //  return (celsius * 18 + 5)/10 + 32; //} //celsius kelvin conversion double kelvin(double celsius) {   return ...

hi, sorry, new , unsure lot of things, need clarification. haven't found information explains how , why things work, "do this, that" i following guide ( arduino-thermistor-temperature-sensor-tutorial ) connect thermistor arduino uno. here temperature sensor information: temp. sensor 2000r +-1% to92 part.no.:   kty81-210 name:   temp. sensor 2000r +-1% to92 description:   2.5mm, 1980...2020ohm, -55...+150°c and here sensor's data-sheet: sensor data-sheet i have connected same way in guide. works , values being serial printed. what don't understand: 1. thermistor's , resistor's ohm value should equal, correct? in case 2000 ohm? 2. thermistor has ptc, i'm guessing have invert math or use ntc thermistor instead correct values? (currently resistance goes temperature goes down) 3. understand code uses steinhart-hart math logic convert resistor value temperature value, need a, b , c coefficients of thermis...
