There is this sensor that breaks down easily but I don't know why. The manufacturer says too much voltage or electrical current can cause problems.
經常會有傳感器損壞，但是不知道原因。制造商說電壓或電流過高會導致問題。

Well, there might be a wire that is accidentally touching to a voltage circuit, or it could be a low resistance value, but the cause for something like this is usually surge noise.
是的。也可以考慮是因為誤接觸電壓電路或者電阻值不足，不過常見原因是浪涌噪聲。

Actually, the sensor is placed in an area that is prone to electrical noise. What should I check to prevent similar problems?
的確，那臺傳感器就在容易產生電氣噪聲的位置。
要檢查哪些點才能防止再次發生呢？
Cindy
First, you need to find out where the noise is getting in. The usual suspects for entry are places like the power line or the output line of the sensor.
首先必須確定噪聲的入侵路徑。噪聲有可能入侵的路徑往往是電源線路和傳感器的輸出線路。
