What should i do the sensor and systems of remote apple is broken

We, just users like you, cannot diagnose that kind of issue remotely, sorry.

I suggest that you make an appointment (*) and have your device inspected at an Apple Store or AASP (Apple Authorized Service Provider) among this list:--> https://locate.apple.com/choose-country-region . After checking it out, they'll give you all the available options.

Regards

(*) You can do it:

• Online:--> Genius Bar Reservation and Apple Support Options - Apple;
• Contacting a local Apple Store or AASP among the list provided above;
• Using the "Apple Store" app, available and downloadable from AppStore.

If you mean your Remote for your Apple TV, then you can use the built-in Apple TV remote in your iPhone, from the Control Centre If you don't see it there, add the button here: Settings → Control Centre → Apple TV Remote
