This kit lets you build a production-style monitoring tool: an ESP32 that reads precise temperature and humidity from a DHT22 sensor, then reports those values to your phone via Telegram. Even better, you can command a relay to switch on a cooling fan, backup system, or warning light just by typing a chat message — exactly the kind of remote control used in professional infrastructure management.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eYou'll assemble the DHT22 sensor and relay module on the breadboard, program the ESP32 to join a Wi‑Fi network and securely connect to Telegram’s bot API, then deploy the unit inside a server rack or enclosed electronics cabinet.
