Three battery‑friendly ESP32 boards read DHT22 temperature and humidity data at remote locations—think off‑grid agricultural monitoring, construction site sensing, or a campus‑scale weather mesh. This kit gives you every chip, antenna, and wire to build the architecture in a single focused sprint.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eA compact LTE gateway that runs its own Wi‑Fi hotspot, MQTT broker, and dashboard. Three ESP32‑powered sensor nodes publish real‑time climate readings from across your site. The Raspberry Pi logs everything locally, pushes data to cloud services if you choose, and remains accessible via private LTE even where broadband doesn't reach.
