赤外線リモコン送信モジュール

説明
– Item name: infrared remote control transmitting module
– Using MOS amplifying circuit, it can directly connect to MCU IO drive, with a current limiting circuit.
– Infrared linear launch distance is 50 meters, which an ordinary infrared tube can not reach.
– Infrared is recommended only for indoor use. Strong light actually has a great influence on the infrared distance.
– Board size: 20mm x 20mm
– Lifespan > 50,000 hours
– Working temperature: -20 – 70 centi-degrees

注：
Used for signal transmission needn’t a radiator. If you need to continue to light up at a high level, need to add a radiator.

The infrared code and carrier are introduced below. If you use a microcontroller to control the transmit data, the transmit waveform should meet the following conditions, which is the standard infrared remote control code format:

The infrared signal also needs to superimpose 38K on the carrier signal before it can be transmitted far.

The following is a step-by-step introduction to the launch waveform.
