Receptor Infrarojo Cubierta Metalica 38Khz TL1838 VS1838

Descripción

Receptor Infrarojo TL1838

Led Infrarrojo

Decodifica cualquier señal a 38 KHz que puede ser de cualquier control remoto infrarrojo TV, modulares, etc.

(regularmente se requiere un microcontrolador para interpretar la señal)

Voltaje: 2.7 Vcc a 5.5 Vcc
Corriente: 0.4 mA a 1.5 mA
Frecuencia: 37.9kHz
Angulo de recepción: 45° a partir de la línea directa entre el transmisor y receptor

Ejemplo de diagrama y código

//Infinite loop
