Arduinos nano wireless sensor network

[adwnis123]

Hello,

I want multiple Arduinos nano connected to an RFs/WiFis modules to read temperatures and send them to a central Arduino connected to an RF/Wifi module... (many routers to one coordinator).

What choices do I have? I need low cost RF/WIFI modules (up to 3-4 euros/wireless module) not Xbees. I would prefer a transmit range 800m - 1000m (and more if it is possible).

Thank you.

If its a noisy environment wifi is not a good choice. check with lora modules

Does LoRa work as point to point connection? Or is something more complicated?

The specified wifi range for typical applications is about 300ft (~100m) although you can extend for a multiple of that when there is no obstacles and no case covering the board (a good reason for choosing modules with external antennas). If you make use of Wifi extenders/routers with high signal strengh, this helps of course.

The ESP8266 as Easyrider83 pointed out is a nice choice in the sense of being a standalone solution, what means, this board can make the whole job itself (communication+measuring), whereas an Xbee - which seems more suited for larger ranges - acts as a peripheral device, needing a local CPU to handle it.

You can use Xbee S2C wireless modules which can be accessed at very higher ranges and you can also use zigmo routers https://store.ncd.io/product/802-15-4-long-range-wireless-modem-with-usb-interface/ in between to strengthenize the network
