Most cheap air quality sensors estimate CO₂ from VOCs. The Sensirion SCD30 actually measures it — using real NDIR technology.

Just published a tutorial on wiring it up with an ESP32 for real-time indoor CO₂, temp, and humidity monitoring. 🌱

No Wi-Fi in the field? No problem. 💡
Recently I built a small LoRa + ESP32 IoT system, and it was really fun to work on.
The main part of the project is REYAX TECHNOLOGY RYLR993 / RYLR998 LoRa modules. I used them to connect remote ESP32 sensor nodes with a central hub over long range.
The data flow is simple:
Sensor Nodes → LoRa → ESP32 Hub → MQTT → MySQL → Web Dashboard
I used a DHT22 and liquid level sensor for the nodes, and built a simple Flask dashboard to see the data live.
No Wi-Fi or cellular connection is needed at the sensor nodes, which makes LoRa pretty interesting for remote monitoring.
I also made a complete tutorial showing the wiring, code and live dashboard.

What are you building with LoRa? 😃
