IR Remote Infrared 38kHz - Universal Mini Controller BLE Micro - Super Compact BLE Module but this one is compactThe diode includes an IR Transmitter Module, sometimes referred to as an infrared light emitting diode. Electrical energy can be directly converted into near infrared by an IR transmitter module. All types of photoelectric switches and remote transmission circuits primarily use light and the radiation that comes from the light emitting device. Although it uses different semiconductor materials, the infrared transmitting tube construction works on a
