Additional Details:

The TSOP35238TS operates on a supply voltage typically between 2.5V and 5.5V. The output signal is a digital pulse width modulated (PWM) signal that corresponds to the received IR signal. The module's internal filter is designed to reject noise and interference from ambient light sources, such as sunlight and fluorescent lighting. The module typically has three pins: VCC (power supply), GND (ground), and OUT (output). The datasheet should be consulted for detailed electrical characteristics, timing diagrams, and application examples. A decoupling capacitor should be placed near the power supply pin to minimize noise and ensure stable operation. The sensitivity of the receiver can be affected by the distance between the remote control and the receiver, as well as the presence of obstacles in the signal path. The TSOP35238TS is a popular choice for remote control applications due to its small size, ease of use, and reliable performance.
