today i learned – thurs 3rd may 2018

have you ever used one of those handheld thermometer guns that you just point at stuff to get temp? 🔫

you know the ones … they use witchcraft to determine temperature from a distance? 🙈 well …

#tdil exactly how infrared thermometers calculate temperature from a distance 🌡

i’m not sure that i explained the above very well … but what i’m on about are those guns that you point at things, hit a button and immediately get a temp reading (without any contact) … this is one –

ever wondered how they work? i have … here’s your answer 😏

basically, infrared thermometers take advantage of the fact that all objects that have mass emit energy in the form of heat.

when you focus your infrared thermometer on an object, it can figure out the surface temperature of an object by calculating the difference between the infrared rays coming off the object and the surrounding area 👍🏻

in more detail, the infrared thermometer works by using a lens to focus light from the object onto a special sensor called a ‘thermopile’.

the thermopile absorbs the infrared radiation and turns it into heat 🔥 the more infrared radiation, the hotter it gets! this heat is then turned into electricity ⚡️

the electricity produced is then sent to a detector and the heat of the object determined! basically – the hotter the object > the more infrared radiation detected > the more heat produced at the thermopile > the more electricity created > the higher the final temperature reading 😎

i kind of preferred it when i was convinced that it was witchcraft 😂 it was certainly simpler than the source that i just read to make this post! 🙈 … hopefully it all made sense? 🤔

either way, i found this super interesting 😁 let me know if you did too!

laters ✌🏻 #tdil


if you’ve never used one of these devices, go find one! 😏 in the meantime, go forth and learn more cool stuff ->here<-
