GP1UX311QS. Receptor infrarrojo 38KHz .
Reemplaza al PNA4602M pin a pin.
IR detectors are little microchips with a photocell that are tuned to listen to infrared light. They are almost always used for remote control detection – every TV and DVD player has one of these in the front to listen for the IR signal from the clicker. Inside the remote control is a matching IR LED, which emits IR pulses to tell the TV to turn on, off or change channels. IR light is not visible to the human eye, which means it takes a little more work to test a setup.
-IR detectors are specially filtered for Infrared light, they are not good at detecting visible light.
-IR detectors have a demodulator inside that looks for modulated IR at 38 KHz. Just shining an IR LED wont be detected, it has to be PWM blinking at 38KHz.
-IR detectors are digital out – either they detect 38KHz IR signal and output low (0V) or they do not detect any and output high (5V).
