The TSOP38140 is an infrared (IR) remote receiver module that can be used for controlling devices wirelessly. The TSOP38140 is an optical sensor-photo detector-remote receiver with features including 38kHz carrier frequency, wide operating range (2.7V – 5.5V), dual-tone modulation and a wide field of view.

The TSOP38140 is based on the mature TSOP384x family of IR receivers. It integrates all the necessary components in a miniature surface-mount package, making it ideal for space-constrained applications. Furthermore, the low operating current ensures optimum performance when used with battery-powered devices.

The TSOP38140 is designed to receive and detect 38kHz modulated IR signals. It features low power consumption and high sensitivity. The receiver consists of an IR sensitive phototransistor along with an opto-coupler, amplifier, and demodulator circuit. Upon reception of a valid signal, it outputs a digital LOW signal. The maximum distance between the transmitter and receiver ranges from 10 to 15 meters, making it suitable for controlling household appliances from a distance.

The receiver works on the principle of an opto-coupler, where the IR sensitive phototransistor senses the modulated IR signal transmitted by the source. The signal is then passed through the opto-coupler, amplifier, and demodulator, which are extremely sensitive to the generated IR frequency. This ensures that only the IR signal with the right frequency is detected. Upon detection, the signal is converted into a digital LOW signal, which can be used to operate external electronic circuits.

Due to its wide field of view and low power consumption, the TSOP38140 is ideal for use in remote control applications. It is suitable for applications such as consumer electronics, home automation, gaming, and robotics. Moreover, its integrated design and wide operating range make it the perfect fit for small portable devices and battery-powered gadgets.

In conclusion, the TSOP38140 is a remote receiver module that can be used to control devices wirelessly. It features a wide operating range, dual-tone modulation, 38kHz carrier frequency, and a wide field of view. Moreover, it produces a digital LOW signal upon detection of the correctly modulated IR frequency, allowing it to operate external circuits. With its integrated design, low power consumption, and wide application field, it is an ideal choice for both portable and battery-powered gadgets, as well as for consumer electronics, home automation, gaming, and robotics.
