RIO IR output + IRM01 low power?

Thanks for the update
Many remote controls have better angle coverage because they have 2 to 3 transmitters behind the IR window

You should also be able to achieve the same angle by using 2 transmitters in parallel

Hi, thanks for your support, i also tried replacing the ir led from the IRM01 with one from a old universal remote and it woks in the same narrow way. I suspect that there is a enhanced led driver used in common remotes that boosts performance. It would be nice if you had that option in your available IR transmitters.

The effective angle of an IR transmitter cannot be boosted by any special driver. The IR is most effective at the centre and rapidly decreases as the angle from centre decreases

The transmitting power ie current depends on the series resistor of the IRM which is 100 ohms. If the current to the IR transmitter is increased the performance at all angles is similarly boosted

Many remote controls have smaller value resistors to boost power and effective angle. For IRM01 because it is an external module we do not use smaller value resistors because programing errors may cause constant voltage to be applied to the IR output and damages the IR as well the output

Using a parallel IR transmitter connected to the same output but pointed slightly different may be a better option

Hi ident,

Thank you for the explanation, i will follow your sugestion.
