Your sensors, live in seconds.

Meca 3D Lab is a free IoT monitor: you pick your sensors (temperature, humidity, CO₂, light, motion, current and 50+ others), the site generates ready-made code for ESP32, ESP8266 or Raspberry Pi, you paste it into your board and the readings show up on a live public dashboard — no server to set up, no account, no hassle.

How it works

1. Generate your code — pick the sensors and name your monitor.
2. Paste the code into your board and plug it in.
3. Share your public dashboard: meca3dlab.com.br/mc-XXXXXX.
