The source says all objects with a temperature emit thermal radiation. That’s the input to the sensor (even if the object is colder than the sensor). That’s why it talks about net flow, because as long as the object is above absolute zero, there’s always an input.I don't care what it says, it says nothing in all coming out. warm reaching out to cold, input minus output. No input all output. I know, just like I said.yep no cold flow to the sensor, just like we said. so still waiting on you jethro.yes, so?
"it may be with a positive sign as well as with a negative sign; that is, energy can flow either from an object to the sensor or from the sensor to the object."
Yup. Net to or away.
A thermal sensor is capable of responding only to a net thermal flux, i.e., flux from the object minus flux from itself toward the object.
It's not my fault that your source says net.
Got any observations, or measurements of spontaneous two way energy flow? Got anything other than the output of unobservable, unmeasurable, untestable mathematical models? Didn't think so.
