TSOP1838 IR Receiving Sensor

The TSOP1838 IR Receiving Sensor receives infrared (IR) signals modulated (encoded) at exactly 38 kHz — the standard frequency used by most TV and appliance remote controls. The tsop1838 ir receiver head runs on just 2.5V to 5.5V and draws only 5mA, so it stays cool even in a always-on project. A non-obvious fact worth knowing is that the TSOP1838 rejects ambient light and fluorescent flicker internally, so it does not need an external filter circuit. One honest limitation is that it only receives signals at 38 kHz and will not respond to remotes using different frequencies. Connect VCC, GND, and the output pin to Arduino and start reading remote button presses right away. StemVolt provide sensor ready to use.
