Description

2PCS 1W 3W 5V High Power Infrared Ray Transmitter Module 940nm LED IR Remote Control Emission Tube Board for RC Toy DIY Part

Specification:

– Item name: infrared ray transmitter module

– Working voltage: 5V

– Power: 1W / 3W (higher the power, longer the transmisstion distance)

– Current: 350MA ( 1W ) / 700MA ( 3W )

– 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: 20 x 20mm

– Lifespan > 50,000 hours

– Working temperature: -20 – 70 centi-degrees

– Angle: 120 degree

Note:

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.

Package Include:

2pcs x 1W module

or

2pcs x 3W module

or

1pcs x 1W module + 1pcs x 3W module

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.
