[0007] Example 1: Overall Structure and Adjustable Sensitivity Function The adjustable sensitivity infrared receiver of this invention includes a receiver body, an infrared filter (1), an IC amplifier (2), a signal processing unit (3), and an adjustable sensitivity module (4). The adjustable sensitivity module (4) includes a potentiometer, which allows the user to adjust the gain of the received signal, thereby adjusting the receiver's sensitivity. This design is suitable for applications requiring sensitivity adjustment based on environmental changes.

[0008] Example 2: Signal Processing and Noise Filtering The signal processing unit (3) integrates a noise filter, which can effectively filter background noise and improve signal clarity and reliability. The infrared filter (1) is a narrowband filter that only allows infrared signals of specific wavelengths to pass through, further reducing interference from non-target signals.

[0009] Example 3: Structural Design and Power Management The receiver body adopts a waterproof and dustproof design, suitable for outdoor and harsh environments. The power management module (5) includes a voltage regulator to provide a stable power supply and ensure the normal operation of all components. The signal output interface (6) supports multiple signal format outputs to adapt to different receiving devices.

[0010] Example 4: Heat Dissipation and Signal Focusing. The receiver body includes a heat dissipation device to prevent overheating caused by prolonged operation. This device includes an aluminum heat sink and a cooling fan. The heat sink is in direct contact with key heat sources inside the receiver (such as the IC amplifier and signal processing unit) to quickly absorb heat, while the fan dissipates the heat outside the receiver. Furthermore, a lens is provided between the infrared filter (1) and the IC amplifier (2) to focus the infrared signal, improving reception efficiency and accuracy.

[0011] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
