Tsop38238 IR Receiver Sensor

For remote control systems, the TSOP38238  is a 38  kHz IR Receiver Module. On a lead frame, a PIN diode and a preamplifier are built, and an IR filter is contained in epoxy packaging. For decoding, the demodulated output signal can be connected directly to a CPU. It has been optimized to block practically all spurious pulses from energy-saving bulbs such as CFLs.

The application circuit diagram for the TSOP38238 IR Receiver module is given below. The Resistor R1 and Capacitor C1 are used to reduce the supply ripples. TSOP38238 consists of a PIN diode, a preamplifier, and an IR filter.

The receiver diode detects all frequencies of IR light, but the filter only lets through IR at 38 kHz. Then the preamplifier modulates the signal and converts it to an electrical signal before sending it to a microcontroller.

Engineers and hobbyists alike use the TSOP382 tiny IR Receiver diode because of its low power consumption and simple-to-use packaging. The TSOP382 is compatible with all popular IR remote control data formats, allowing it to be utilized with a wide range of IR remote controls. It may be utilized with both 3.3V and 5V power supplies because the working voltage ranges from 2.5V to 5.5V.

In terms of size, the TSOP38238 is comparable to a standard plastic-packaged transistor and is suited for all types of infrared remote control and transmission. So, if you're seeking a low-power IR Receiver diode, the TSOP38238 might be the one for you.
