Temperature Correction: Get Accurate Wall Surface Temperature

AI Thread Summary
The discussion centers on correcting temperature readings from an ibutton sensor attached to a stainless steel surface exposed to sunlight. The user seeks methods to account for the impact of solar radiation on the temperature data collected over four months. Suggestions include shading the sensor to compare readings in sunlight versus shaded conditions, as well as analyzing data from cloudy days compared to clear days. The user has access to average irradiance, specific heat values for stainless steel 305, and concrete wall temperatures. Effective correction methods are essential for accurate wall surface temperature assessment.

Dear All,
I have collected temperature data for a period of about 4 months with a device called ibutton attached to the surface of a concrete wall. My problem is the button is made of Stainless steel 305 and exposed to sunlight.
I am interested in obtaining the wall surface temperature and at the same time i know the effect of the sunlight would affect temperature readings (if i am not wrong).
does anyone know or have an idea on how i can correct these readings if i have to?
 
Science news on Phys.org
Data available to me at the moment are: average irradiance of the location, specific heat of the stainless steel 305 and that of the concrete wall (including temperature values)
 
Can you shade the temperature sensor and compare readings in and out of sunlight? Or can you compare readings on cloudy days vs clear days?
 

Thread 'Condensate rate of water for an air conditioning cooling coil'

I need to calculate the amount of water condensed from a DX cooling coil per hour given the size of the expansion coil (the total condensing surface area), the incoming air temperature, the amount of air flow from the fan, the BTU capacity of the compressor and the incoming air humidity. There are lots of condenser calculators around but they all need the air flow and incoming and outgoing humidity and then give a total volume of condensed water but I need more than that. The size of the...

Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'

Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...

Thread 'Entropy and configurations of microstates'

I was watching a Khan Academy video on entropy called: Reconciling thermodynamic and state definitions of entropy. So in the video it says: Let's say I have a container. And in that container, I have gas particles and they're bouncing around like gas particles tend to do, creating some pressure on the container of a certain volume. And let's say I have n particles. Now, each of these particles could be in x different states. Now, if each of them can be in x different states, how many total...
