Infrared Transmitter and Receiver Module


– Operating voltage: 4.5 – 5.5VDC
– Operating Current: 50mA (max)
– Emission angle: 45 degrees
– SIG pin current: High level 0.4mA (max),
low level 1.4mA (max)



This is infrared receiver module can receive the modulated infrared signal of 38KHz that is sent by the IR transmitter module and demodulate it into logic level, ie, when it gets the modulated infrared signal, it outputs one negative pulse and returns to normalcy (High level).
