Universal Infrared Receiver VS1838 TL1838 VS1838B

Use this simple IR receiver for infrared remote control of your next project. With low power consumption and an easy to use package, it mates well with embedded electronics and can be used with common IR remotes.

The TL1838 is a miniaturized receiver for infrared remote control systems. A PIN diode and a preamplifier are assembled on a lead frame while the epoxy package acts as an IR filter. The demodulated output signal can be directly decoded by a microprocessor. The TL1838 is compatible with all common IR remote control data formats.

Remark
1.VCC voltage module operating voltage and good power filtering;
2.Great influence on the antenna module reception, preferably connected to the 1/4 wavelength of the antenna, typically 50 ohm single conductor, the length of the antenna 433M of about 17cm;
3.Antenna position has also affected the reception of the module, the installation, the antenna as possible straight away from the shield, high pressure, and interference source; frequency used to receive, decode and oscillation resistor should match with the transmitter.
