So my project is to create a distance sensor that reads distance, controlled via an android/ios phone with an app via cable. Since one of the requirements is to measure atleast 200m, this sensor would need to be quite powerful and thus power hungry reducing the phones battery life. Another goal is it has to be as small as possible and last a few days.
whats the smallest arduino module that would have to support atleast spi,i2c or uart for the sensor and USB?
since ideally i want to use a smaller module something like the **nano or other small arduino ** is much more ideal than the uno given they dont have a dc port, is it possible to implement this like above, via other means eg. a y type usb splitter, where one side connects to the phone the other a powerbank?
can someone recommend some laser distance sensor that can read aleast 200m?
What has your research shown so far? FYI it appears you are dumping your project on us. What did you find in distance measurement devices. What technology are you looking at. Depends on the USB version and how you are going to use it. Your Amazon link does not work. You can quickly search the web for the smaller arduino product that will do what you want, they are well documented. You can do the port thing, it is a relative simple engineering task, design it and we will help. Egismos makes laser modules that will do what you want. We have no idea of what resources you have.

Now that that you mentioned it it really does lol,
I had done some reasearch what I Initially was thinking was using the dc barrel port, with a dc barrel to usb cable and power it via a regular power bank, with the standard Arduino UNO usb port as data to the phone only. But i realise the dc barrel must be 7v up and it doesnt really work with the power bank there I would require a setup circuit and it would result in a bigger size weight etc..
So instead i was thinking of using an Arduino nano, with a bluetooth module, using the bluetooth to send and recived data to a Bluetooth controller app instead of my previous idea above which would likely require me to build my own app. Then usb power pank to power the NANO directly. The sensor i am planning to use is a dfbot TF03 180m which is a UART connection https://www.dfrobot.com/product-1964.html would a regular power bank be possible to power this sensor and the arduino+bluetoth module?
