IR from remote itself

Hello,

yes.
But
see the comment here, please.
Additionally:
Acoording to the datasheet, the used IR-LED in the remote SFH4045 has VF~1,5V at 70mA.
It’s supply voltage is 1,8V only, in series with the switching Mosfet (unknown type) and the 10 Ohms resistor. Even if the Mosfet has an voltage drop of 0V, the resulting current through the LED will be 30…40mA or lower. This will result in a optical power lower than 25mW in a very narrow radiant angle of 18°.
So I wouldn’t expect any miracles…

Cheers, tiki
