Infrared emitter diode - an infrared transmitter for own circuits
Working with infrared transmitters and receivers takes nowadays in a variety
of applications, such as
remote control
TV set
data transmission
and much more
For selected system boards of myMCU products there is an optional interface
for infrared receivers and transmitters. This interface is not equipped;
they can be added individually and independently.
We recommend as a receiver the Infrared receiver (TSOP38238)
and as a transmitter the infrared emitter diode with a series resitor 220 Ω, which is described here.
infrared receiver
properties emitter diode:
GaAs LED with high efficiency
Peak wavelength: λ p = 950 nm
forward current: 100 mA
current surge: 2 A
forward voltage: 1,3 V / 2,2 V
switching times: 800 ns bei 100 mA; 400 ns bei 1,5 A
Note:
For the use on myAVR products and myXMC products you need only the leaded resistor;
For the use on mySTM32 products you need only one SMD resistor.
One of the both design remains.
