Many companies in the household appliance industry use infrared receivers, but if they want to play their due role, they must purchase infrared receivers that meet corporate standards. Many companies are paying attention to the purchase standards of infrared receivers. Let’s introduce it in detail, let’s go and take a look!

　　 Criterion 1: Receiving distance meets the requirements

　　 The receiving distance of the infrared receiving tube is a rigid index, which cannot meet the requirements that can't be met no matter how cheap it is. Therefore, when purchasing an infrared receiving tube, the distance requirement must be put forward to the supplier first.

　　 Rule 2: Receiving angle to choose the shape of the bridge of the nose

　　 Generally, the dot-shaped receiving angle of the infrared receiving tube will be larger, and the angle of the small dot is larger than the angle of the large dot. When purchasing an infrared receiver tube, if the angle requirement is not high, it is recommended to use the nose bridge type to reduce the cost.

　　Criterion 3: Fully consider anti-interference

The anti-interference ability of the infrared receiver has been fully considered in the design, but the interference cannot be completely avoided and can only be reduced as much as possible. The improvement of the anti-interference ability will generally reduce the receiving distance. Therefore, when purchasing an infrared receiver, you must weigh the remote control. The relationship between distance and anti-interference distance.

　　 Rule 4: Good compatibility

Compatibility should also be considered when purchasing infrared receivers. Although commercially available infrared receivers generally have similar compatibility, there is basically no big difference. If the requirements are not met, we need to pay attention to see if there is a problem with compatibility.
