LPSS22DF accuracy between -15°C and 60°C

[ljm]

Hi

I'm currently using your LPS22DFmodule to measure pressure and I saw in the datasheet that the temperature accuracy is  ±1.5 °C (T = 0 to 80°C). My working range is between -15°C and 60°C. Could you please give me the accuracy of this sensor in the range -15 to 65°C?

Hi,

hello @AScha.3 

thanks for replying.

I'm speaking about the temperature accuracy.. in the datasheet it is  ±1.5 °C (T = 0 to 80°C), but my working range is betwwen -15°C   and +60°C... just if it's possible i want to know the accuracy is the same between -15°C and 0°C or h

greater than the accuracy betwwen 0°C and 80°C ?

Thank you in advance

Its not specified, so test it yourself, to know for sure.

Anyway at +/-1,5°  this is more guessing "temp. is about" , so if you want measure temperature, take a temperature sensor to do this (and not a pressure sensor).

I use the ENS210 , temp. + humidity :

 

Or a pressure + temperature sensor, like BMP280 (or BME280 etc. ); this can with some interpolation give a temperature resolution of 1/1000 ° !  (I tried, is funny, you can see when your go to the table, the bmp280 is there, temperature rising about 0,003° - from body IR radiation ! )

Hi @ljm ,

We tested few parts and I confirm you that the accuracy was around 2°C but consider that we considered a limited number of pcs and thus this value can't be guaranteed in production.
