Remote: 21 Key Mini Infrared remote control. This general purpose ultra-thin 38Khz universal infrared remote control, uses NEC encoding format.

TSOP Sensor: The TSOP1738 is a infrared receiver tuned to react only to IR of frequency 38 kHz. This IR sensor module consists of a PIN diode and a pre amplifier which are embedded into a single package. The output of TSOP is active low and it gives +5V in off state. When IR waves, from a source, with a centre frequency of 38 kHz incident on it, its output goes low. It is perfect for making obstacle sensors and to accept signals from most IR remotes.
