temperature

I am developing an android app for my project, I need to find room temperature as part of it. I am using Droid 2 A955 model for testing. My Questions are: What sensors need to be available in my Android phone to perform this temperature sensing task? Can Ambient Light Sensor (available in Droid 2) help in doing this task? Is there any Android api to find/sense room temperature programmatically in my android code? Thanks in advance for your help. Otra To answer all three of your questions in one fell swoop, no, I don't believe so. There can be a temperature sensor in android devices, but it

I am interested in a way how to read GPU temperature (graphics processing unit, main chip of graphic card), by using some video card driver API? Everyone knows that there two different chip manufacturers (popular ones, at least) - ATI and nVIDIA - so there are two different kinds of drivers to read temperature from. I'm interested in learning how to do it for each different card driver. Language in question is irrelevant - it could be C/C++, .NET platform, Java, but let's say that .NET is preferred. Anyone been doing this before? For nVidia you would use nvcpl.dll . Here's the documentation:

i have this problem from a beginning c sharp book this for conversion between Fahrenheit and Celsius. private void button1_Click(object sender, EventArgs e) { float fahr, cel; if (Celsius.Checked == true) { fahr = float.Parse(textBox1.Text); cel = (5/9)*(fahr-32); richTextBox1.Text = "The Degree in Celsius is:" + cel.ToString() + Environment.NewLine + "cool isn't it!?"; } else if (Fahrenheit.Checked == true ) { cel = float.Parse(textBox1.Text); fahr = ((9 * cel)/5)+ 32; richTextBox1.Text = "The degree in Fahrenheit is:" + fahr.ToString() + Environment.NewLine + "cool is it!?"; } when i want to

I retrieved battery temperature and voltage information using the intent Intent.ACTION_BATTERY_CHANGED and the values I got are pretty weird. I could not get any clue: temperature=270 and voltage=3782 ! What are these values? Do they have any units like celsius, fahrenheit or milli or micro volt?

Sensor Type TYPE_TEMPERATURE has been deprecated [since Android 2.3] probably which was giving info about CPU temperature. Now we have Sensor Type TYPE_AMBIENT_TEMPERATURE which will provide us room temperature (none of my use, & btw not all devices&/Android versions support it) I checked few apps which measures CPU temperature. Probably they're reading system files. I tried locating, in some devices I'm able to locate it inside following path: sys/devices/virtual/thermal/thermal_zone0/temp The structure bit varies from vendor to vendor & also the unit of measurement. fine! But in many devices

Someone knows an algorithm that gets temperatue in Kelvin/Celsius and returns RGB? Like in thermal cameras. I found some links : http://www.brucelindbloom.com/index.html?Eqn_XYZ_to_T.html http://www.fourmilab.ch/documents/specrend/specrend.c But i cant figure what XYZ color is ? I only have temperature in Celsius.. i can convert it to any temperature Temperature Conversion Formulas UPDATE: Blackbody Color Datafile I have found this.. but those Kelvin degrees are impossible.. i mean red suppose to be hot.. so why 8000k is blue and 1000k is red... The best option is to use an image with GetPixel

This question already has an answer here: C program to convert Fahrenheit to Celsius always prints zero 8 answers My temperature conversion program in C keeps outputting 0 when I attempt to convert Fahrenheit to Celsius. The conversion from Celsius to Fahrenheit seems to work just fine. I have done the exact same thing for both functions and portions but I keep getting 0 for the second conversion. Can someone please help me or tell me what I am doing wrong? #include <stdio.h> //Function Declarations float get_Celsius (float* Celsius); //Gets the Celsius value to be converted. void to
