I’m about to buy equipment for a chemical experiment in which I need to know (as fast as I can) the temperature of the surface of a small volume of liquid. I’ve seen the sensor used (https://theorycircuit.com/infrared-thermometer-arduino/) to obtain measurements every 500ms.
I wonder if I could lower that time to at least 300ms and what would be the minimum. A precision between 0.1 and 0.2 degrees celsius would be acceptable. I read the datasheet but I can’t make a lot of sense out of it.
Sure, as long as your microcontroller can poll at the frequency desired - this is handled in the code; you would likely simply change the ‘delay’ and other timing metrics to your use-case. Decrease the ‘delay’ amount
The MLX90614 offers a standard accuracy of ±0.5˚C around room temperatures. A special version for medical applications exists offering an accuracy of ±0.2˚C in a limited temperature range around the human body temperature.
