OPT4001-Q1: Operating temperature dependency at illuminance measurement result

Kazuki Kuramochi

Part Number: OPT4001-Q1

Hello Expert,

Our customer want to know about the trend for the operating temperature and illuminance measurement result.
Is there dependency between this parameters?

I understand our device is designed for guarantee datasheet described performance over operating temp condition and other trend isn't guaranteed.
We just want to confirm whether there is any specific trend between operating temp and measurement result as design reference.

Best regards,
Kazuki Kuramochi

Hi Kuramochi-san,

When measuring the illuminance, it is important to have a wait time to let the light source thermally stabilize. This is mentioned in our Precision Labs video "Testing Light Sensors and Prototype Systems".

So generally there will be some dependency on temperature with illuminance result, but we do not have spec for this.

Hi Jalen,

We don't request you to issue temperature dependency against illuminance measurement result.
Could you please consider to issue opinion for the temperature dependency?(e.g. high temp condition will cause higher illuminance measurement result rather than low temp condition and so on...)

Best regards,

Kuramochi-san,

We dont have any data or spec for this use case.
