It has the functions of shielding against light source interference and fixed light interference with specific frequencies, thereby improving the stability and sensitivity of the product's signal reception.
[0022] As an embodiment of the present invention, the shielding shell is further provided with epoxy resin fixing strip 22 and epoxy resin fixing block 23, which are used to fix the single spherical epoxy resin body structure 1.
[0023] As one embodiment of this utility model, the built-in IC signal shielding bracket 3 is connected to pins 6.

Therefore, a shielding shell is added to the product to reduce interference from light sources on the infrared receiver module system, thereby improving the functionality of the infrared receiver.
