I bought a laser receiver like below pictures but it grilled for lack of keying: s.
Does anyone know the reference of the receiving module ( transparent with 3 pins )?
I found this but I do not know if it fits: http://www.ttelectronics.com/optoelectronics/ir-sensors/photologicr-sensors
If so, which reference to choose?
Incidently if you provide links to Aliexpress, best to warn people. The links flips the viewers default language across to the language used to provide the link. The viewer then has to revert their own view of Aliexpress back to their own language.
Well, not much to know about this device. Shine the laser on it, and the Out pin goes HIGH. No laser and it hangs LOW. There's no intelligence, here, so no need for a modulated beam. But, because of that, it's more likely to react to bright ambient light.
Here's a video that seems to do a good job of explaining how to use the thing:
So, whatever it is, it needs a power connection -- so it probably has some internal active circuitry, to, perhaps, "Digitize" the analog output of the photo device.
