I bought new sensor of same model.
But just little careful to choose dust model.
Because dust sensor is not same with different Xiaomi Air Purifier model, Pro, 1, 2, etc.
You need to check sensor model for your Air purifier model.
After that, just do it follow this video.
Don't throw big money.
Do it by yourself.
