Against any racial discrimination, I think that Lego City citizens have a right to know the weather.

In the quest for a true “Internet of Things” solution, a Cactus Micro Rev2 – Arduino with an ESP8266 WiFi module built-in is perfect for the scope. This is a huge time and space saver, costs only a few dollars and is perfect for small sensor projects.

Here the whole project and the required components to help your population’s life in LEGO City:

•  Microcontroller
  • Cactus Micro Rev2 – Arduino w/ ESP8266 WiFi built-in
• Display
  • LCD 16×2
• Sensors
  • DHT11- Humidity and Temperature
  • Photoresistor – Light
• Messaging
  • MQTT
  • Mosca – MQTT broker
• Data Storage
  • MongoDB
• Data Analysis
  • Google Chart
• Programming
  • Arduino Sketch (C++)
  • Node-RED
