Is it possible to get the consumption of that part RB-Dfr-25 in amperage?

I need to know approximately how long it will last on a 9v battery.

Thanks

Hello @julienrobert

The Gravity Ambient Light Sensor uses a PT550 phototransistor. I looked at the manufacturer’s website and they have this datasheet. I don’t know what language that is but I’m pretty sure the information you need is on page 3. I used the google translator and got this (EA = μA).

And I also found this datasheet online:

I hope that can help you out!

Thanks. I found Maximum power consumption 70mW. I think at 5 volt it means 14mA.
