Mini 38KHz IR Emitter Transmitter & Receiver Sensor Module for Arduino
The Infrared Emitter is based on the infrared emission infrared emission control module 940£¬ the infrared signal emitted by the transmitter tube 940nm wavelength£¬ the signal can be acquired infrared receiver module is a few meters away and demodulation£¬ encoding and decoding process can be achieved with the remote control function. Features: (1). Level control interface£¬ power supply for 5V or 3.3V; (2). High drive currents needed to pull small; (3). In accordance with the direction of the tube can be launched manually adjust the actual application requirements; (4). 4 M2 screws positioning holes for easy installation. The Infrared Receiver is based on HL-A838 integrated infrared receiver modules£¬ IR transmitter module can receive incoming 38KHz modulated infrared signal£¬ and demodulated into logic level£¬ When it receives the modulated infrared signal then output low level£¬ otherwise output high level. IR remote control can be completed by using application of codec. Features: (1). Funny and easy to use; (2). low-power£¬ wide-angle and long distance reception; (3). Supply voltage can be 3.3V~5.5V; (4). Output matching TTL£¬ CMOS level; (5). 4 M2 screws positioning holes for easy installation.
