The infrared-receiver Module use the 1838b as the infrared receiving head which receives infrared signals and can independently receive infrared ray and output signals compatible with TTL level. It's similar with a normal plastic-packaged transistor in size and it is suitable for all kinds of infrared remote control and infrared transmission.
The schematic diagram of the Module is as follows:
