CENTRAL CODE STATIONCentral Labs — Hardware & Electronics
ESP32 Environment Monitor
A small network of ESP32-based sensor nodes reporting temperature, humidity, and air quality to a self-hosted dashboard in real time.
Central Labs exists partly because our team wanted to understand embedded hardware the way we understand software — by building something real with it. This project started as a way to monitor air quality across our own office, and grew into a small reusable platform for sensor-driven monitoring.
How it works
Each node is built around an ESP32 microcontroller wired to temperature, humidity, and particulate sensors. Nodes publish readings over MQTT to a lightweight Go service, which stores time-series data and serves it to a small real-time dashboard.
What we learned
Working close to the hardware layer sharpened our thinking about reliability in software too — a sensor node that silently drops readings taught us more about designing for graceful degradation than any backend outage ever has.
