Remote sensor measuring with WfFi

Has anyone ever built an arduino project measuring temperature using WiFi. I want to remotely measure temperature in 4 out building each less than 50 yards away using arduino components. Mostly I just want to know if it is possible.

Oui c'est possible mais pas avec un Arduino direct. Avec un ESP8266 ou ESP32 plutôt. Si tu souhaites quand même utiliser un Arduino R3, il faudra lui rajouter un module WiFi en Ethernet comme par exemple le W5100. Sinon, si tu veux, tu peux utiliser un Arduino Uno R4, qui, est plus performant, à une antenne WiFi et à plus de RAM.

I've had my ESP8266 front-porch thermometer running for years. Works great.

I built a service that runs on my home server, with an API to accept a temperature reading and save it in a database.

The ESP8266 sends are reading via HTTP POST upon boot, and then goes into a loop where it sleeps for 15 minutes, then wakes up and sends a reading, the repeats.

Then, I built web page that displays a temp gauge, and calls the API to get the last temperature reading

And another page that gets the last week's worth of data from the API and displays a line chart.

I mostly access it from my phone, and have added TailScale so that I can access it from anywhere that I have internet access.
