Desk Climate Monitor

An ESP32 + sensor board that logs temperature, humidity and CO₂ at my desk and pushes it to a tiny dashboard. My first proper electronics-meets-software build.

Second example — showing a hardware/engineering project alongside the software one, so you can see how the kind tag colour-codes them.

Why I built it

Swap in your real story. The tone across the whole site should sound like you, not a spec sheet.

The build

Mix prose with photos of the process — people love seeing the messy bench shots, not just the finished render.

Breadboard prototype

A bit of firmware:

void loop() {
  float t = sensor.readTemperature();
  float h = sensor.readHumidity();
  publish("desk/temp", t);
  publish("desk/humidity", h);
  delay(60000);
}

Result

What worked, what surprised you, what’s next.
