This advanced kit gives you everything to build a true star topology using ESP-NOW, the low-latency protocol that leaves Bluetooth and Wi-Fi behind for sensor arrays. It's the ideal backbone for smart agriculture prototypes, campus IoT projects, or mastering mesh communication at the packet level.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eYou'll create five battery-powered ESP32 sensor nodes, each transmitting DHT22 temperature\/humidity and soil moisture readings over ESP-NOW to a central gateway. The gateway ESP32 aggregates this multi-source data and updates all 10+ live sensor values on a crisp 1.8-inch TFT screen. The entire network is peer-to-peer, with no router required, and can be deployed indoors or across a field.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Learn\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eESP-NOW communication protocol, packet structure, and MAC-based addressing\u003c\/li\u003e\n  \u003cli\u003eDesigning a robust star network topology with one-to-many data flow\u003c\/li\u003e\n  \u003cli\u003ePrecision interfacing of DHT22, capacitive soil moisture sensors, and TFT displays on ESP32\u003c\/li\u003e\n  \u003cli\u003ePower management for 18650-powered edge nodes and data aggregation techniques\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eKit Contents\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eComponent\u003c\/th\u003e\n\u003cth\u003eQuantity\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eESP32 Dev Board\u003c\/td\u003e\n\u003ctd\u003e6\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDHT22\u003c\/td\u003e\n\u003ctd\u003e5\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSoil Moisture Sensor\u003c\/td\u003e\n\u003ctd\u003e3\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e1.8in TFT ST7735\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e4.7k?
