This article claims the the DHT22, a slightly upgraded version of the DHT11, is able to handle wires of up to 30M when powered with 5V. I don't think power is the issue, as much as the ability of the signal line to carry the signal over that length of wire. Just use a 5V Arduino board and you should be ok. (It looks like each one only needs about 1.5 mA, so ...

DHT11 sensor uses a "single-Wire" protocol with open drain IOs. so it's fine for cable to be long. use a lower value Pull-up resistor for Data line of DHT11. the datasheet says a 5K pull-up resistor is enough for up to 20m wire length. the process of reading a sensor can't be paralleled. you have to read them one at a time, store them on a local variable and ...

For AI use there is the K210 based sipeed maix board. Dual core 400MHz, plus an AI coprocessor.

I may handle this case like using pyserial library I just log the data to my laptop and then using python to do your Advance AI code part. Send the sensor data as a combined String via Arduino serial port. read it using pyserial library add a data logging mechanism if you need or parallel process the data you gathered serially by cast them to their own data ...

It sounds like you need a lot of compute power. You can either put the sensors and AI on one device (and @majenko's suggestion of a Raspberry Pi would be a direction to pursue) or you need two devices, one to manage the data collection - Arduino, perhaps - and one to do the AI. We don't know enough about your post-processing and AI to make a good ...

I suggest that you use a different family of processor than the 8-bit AVR chips that are supported by the Arduino IDE (and please fix your spelling errors, all the double-letter words are very distracting). A good example might the the Teensy 3.2 or Teensy 3.6 offered here https://www.pjrc.com/ "Version 3.6 features a 32 bit 180 MHz ARM Cortex-M4 ...
