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 @Federica Bossi 

Thanks for replying,

I've seen that I can use it between -45°C and 80°C but I need its accuracy in this range? the range of my application is -15°C to 60°C and I need a temperature accuracy that doesn't exceed 2°C.

You can take a temperature sensor or a reference sensor and measure the temperature and than compared the obtained results with those given by the LPS22DF.

Hi @Federica Bossi

thanks for replying,

yes, i tested 10 samples of LPS22DF at the range (-15°C to 0°C) and i founded that there is 2 samples that  its accuracy temperature exceeded 2°C

Thanks

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.
