The TSOP 1838 is a member of IR remote control receiver series. 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. 

This infra-red sensor can be used with both Arduino and Raspberry Pi micro-controllers.It can be used to decode infra-red signals from remote controls such as a TV remote or some RC vehicle remotes. It is especially designed to be reliable and easy to use with infra-red filters and a pre-amplifier IC built in.  The infra-red sensor is just the sensor and you will need to connect it to the appropriate input and output pins on the Arduino or Raspberry Pi for it to function. This is simple as it only has 3 connections, power, ground, and signal out.  This sensor is only a receiver and not a transmitter!

This package includes a universal remote that works with the TSOP 1838 sensor module.
