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.
- makapuf 7y agoEsp8266 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.
