OPT3001-Q1: long term stability

Roland Melad

Part Number: OPT3001-Q1

HI,

We have a customer who is inquring regarding stability of the sensor itself after calibration.

So lets say that the corrected measurement for a given input is 100 lux . How much will this measurement for the same exact input differ in the future. Do you have any data on this long term variation?

Regards,
Roland

Hi Roland,

What type of calibration are you referring to?

hi Alex,

Thank you for your response. Our customer is in need of a better accuracy than 10%, hence we have advised them to calibrate as stated in the E2E post link below.

Now, he would like to confirm if he calibrates the device. Will the calibration hold for how long? Are we expecting any error as time goes by?

Regards,

Roland

Hi Roland,

Calibration performed will not have to be redone as the device is stable over time. This is how our internal calibration works as well.

Best,

Alex
