Wifi, RF, or Bluetooth: Best way to connect multiple sensors to a central hub


I’m building a wireless sensor array where I will have multiple multiple sensor modules communicating with a central hub (Raspberry Pi or ESP). I’m having trouble deciding whether I should go with Wifi, RF, or Bluetooth as a communication protocol between the central hub and all of the sensors.

The sensors will need a range of about 10-15ft. The sensors will be battery powered and only need to work for about 15 minutes. They will be rechargeable, so I’m not worried about the power constraints of Wifi.

I’m have no experience with wireless communication and am not sure where to start when it comes to picking hardware. Any pointers would be greatly appreciated!
