[0024] Reference Figures 1 to 6 This utility model discloses a high anti-interference light infrared sensor receiver, comprising: a substrate 100, a sensor 200, pins 300, a shielding cover 400, and a housing 500; the sensor 200 is disposed on the substrate 100; the pins 300 are disposed on the substrate 100 and electrically connected to the sensor 200; the shielding cover 400 is connected to the substrate 100, and the substrate 100 is provided with the shielding cover 400, which is provided with a plurality of shielding meshes configured to shield interference light; the housing 500 is disposed on the outside of the substrate 100, and the housing 500 covers the substrate 100 and the sensor 200. In this embodiment, the substrate 100 is provided with the shielding cover 400, which has five bends, bending the shielding cover 400 into a "cover shape" and forming a closed space with the substrate 100. The sensor 200 is disposed in this closed space, and each of the five faces formed by bending the shielding cover 400 is provided with a shielding mesh.

[0025] Reference Figure 3 The shielding cover 400 covers the substrate 100. The shielding cover 400 can block the interference light from the front and the interference light from the four sides, thus achieving the shielding of the interference light.

[0026] Reference Figure 6 The shielding cover 400 is integrally formed with the substrate 100, and shielding mesh is provided on all five sides of the shielding cover 400.

[0027] The substrate 100 is configured to mount the sensor 200, which is electrically connected to the pin 300. The substrate 100 carries the pin 300 and the connection line between the pin 300 and the sensor 200 (not shown in the figure). The sensor 200 is configured to receive signals and transmit signals through the pin 300. The shielding cover 400 is configured to block interference light and improve the sensitivity and accuracy of the sensing.
