I highly recommend the ESP8266 and ESP32 once you're a little more familiar with the arduinos.

They have Wifi, and the ESP32 is actually very powerful and has two cores. They make for great DIY home automation/IOT devices and are pretty easy to work with.

Second this. The ESP8266 (a nodeMCU) is about as powerful as an Arduino Uno, is about half the size of a credit card, is very thin and costs around $3.

The wifi part is the biggest advantage. You can send sensor data directly to your server via simple http requests.


Esp8266 is way more powerful than an arduino Uno. It's got a 32bit 96MHz proc with 96k of ram and Wifi, often coupled with 4MB flash. Uno has 32k of flash 2k ram and (from memory) 20MHz 8bit cpu.


The Wemos ESP8266 was a fun start. The only thing I found a bit tricky, iirc, is the limited number of pins, and figuring our the mapping from D0..8 to ESP8266 number. This answer helped: https://community.blynk.cc/t/solved-wemos-d1-not-working-wit...
