It's ideal for Indian college hostels, CBSE school projects, or anyone tired of waking up to a freezing room. You'll read real-time environment data and transmit precise infrared commands - turning a plain air conditioner into a self-regulating climate system.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eYou'll assemble a compact circuit on a breadboard that combines an ESP8266 microcontroller with a DHT22 temperature\/humidity sensor. The system learns your AC's infrared remote commands using the included TSOP1738 receiver, then retransmits them via high-power IR LEDs to turn the AC on\/off and adjust settings. Once programmed, it continuously monitors the room and sends appropriate IR signals to keep the temperature at your chosen setpoint.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Learn\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eDecoding and reproducing IR remote control signals for air conditioners\u003c\/li\u003e\n  \u003cli\u003eInterfacing the DHT22 digital temperature and humidity sensor with NodeMCU\u003c\/li\u003e\n  \u003cli\u003eBuilding a transistor-based IR blaster circuit for reliable long-range transmission\u003c\/li\u003e\n  \u003cli\u003eProgramming an ESP8266 to make autonomous decisions based on real-time sensor data\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\u003eESP8266 NodeMCU\u003c\/td\u003e\n\u003ctd\u003ex1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDHT22\u003c\/td\u003e\n\u003ctd\u003ex1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eIR LED 940nm\u003c\/td\u003e\n\u003ctd\u003ex2\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eTSOP1738 IR Receiver\u003c\/td\u003e\n\u003ctd\u003ex1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBC547 Transistor\u003c\/td\u003e\n\u003ctd\u003ex2\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e100?
