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. Usage of the IR modules : This 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; Funny and easy to use low-power wide-angle and long distance reception; Supply voltage can be 3.3V~5.5V; Output matching TTL CMOS level; 4 M2 screws positioning holes for easy installation
