Place the sensor-equipped transmitter in a room, duct, or near an AC vent and read real-time values on the LCD receiver — perfect for diagnosing air conditioner performance, checking ventilation efficiency, or logging data for a school science project. This project introduces you to IoT fundamentals and wireless communication without the complexity of Wi-Fi or Bluetooth.\u003c\/p\u003e\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eYou’ll assemble a remote sensor node that sends temperature and humidity data every second to a base station. The base station displays the readings on a 16x2 LCD, so you can monitor HVAC performance without running wires. You’ll also learn to power both units with 9V batteries, making it truly portable for field measurements.\u003c\/p\u003e\n\u003ch2\u003eWhat You'll Learn\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eWiring and configuring NRF24L01 wireless modules for reliable 2.4GHz communication.\u003c\/li\u003e\n\u003cli\u003eCalibrating the DHT22 digital sensor for accurate temperature and humidity measurements.\u003c\/li\u003e\n\u003cli\u003eUsing I2C backpack to drive a 16x2 LCD with minimal Arduino pins.\u003c\/li\u003e\n\u003cli\u003eDesigning a wireless sensor network protocol, including packet structure and error handling.\u003c\/li\u003e\n\u003c\/ul\u003e\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  \u003cp\u003eHVAC — Two Arduinos with NRF24L01 radio send DHT22 readings wirelessly to LCD.\u003c\/p\u003e\n  \u003ch4\u003eWhat's in this kit\u003c\/h4\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003ca href=\"\/products\/uno-r3-ch340g-atmega328p-board-arduino-compatible\"\u003eArduino Uno R3\u003c\/a\u003e x2\u003c\/li\u003e\n    \u003cli\u003e\n\u003ca href=\"\/products\/nrf24l01-24ghz-wireless-transceiver-module-compoden\"\u003eNRF24L01\u003c\/a\u003e x2\u003c\/li\u003e\n    \u003cli\u003e\u003ca href=\"\/products\/dht22-temperature-humidity-sensor-module-accurate-readings\"\u003eDHT22\u003c\/a\u003e\u003c\/li\u003e\n    \u003cli\u003e\u003ca href=\"\/products\/16x2-lcd-display-module-16x2-character-blue-backlight\"\u003e16x2 LCD\u003c\/a\u003e\u003c\/li\u003e\n    \u003cli\u003e\u003ca href=\"\/products\/i2c-backpack-pcf8574-i2c-adapter-for-lcd-displays\"\u003eI2C Backpack\u003c\/a\u003e\u003c\/li\u003e\n    \u003cli\u003e\n\u003ca href=\"\/products\/capacitor-variety-pack-6-values-100nf-to-470uf-30-pieces\"\u003e100nF Caps\u003c\/a\u003e x10\u003c\/li\u003e\n    \u003cli\u003e\n\u003ca href=\"\/products\/capacitor-variety-pack-6-values-100nf-to-470uf-30-pieces\"\u003e10µF Caps\u003c\/a\u003e x4\u003c\/li\u003e\n    \u003cli\u003e\n\u003ca href=\"\/products\/resistor-variety-pack-100-pcs-10-values-14w-carbon-film\"\u003e10kΩ Resistors\u003c\/a\u003e x5\u003c\/li\u003e\n    \u003cli\u003e\n\u003ca href=\"\/products\/breadboard-standard-bundle-830400-tie-points-for-prototyping\"\u003e400-pt Breadboard\u003c\/a\u003e x2\u003c\/li\u003e\n    \u003cli\u003eM-M Wires x30\u003c\/li\u003e\n    \u003cli\u003e\n\u003ca href=\"\/products\/9v-battery-snap-connector-with-15cm-wires-compoden\"\u003e9V Battery Snap\u003c\/a\u003e x2\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n\n\u003cscript type=\"application\/ld+json\"\u003e\n{\n  \"@context\": \"https:\/\/schema.org\",\n  \"@type\": \"FAQPage\",\n  \"mainEntity\": [\n    {\n      \"@type\": \"Question\",\n      \"name\": \"What is included in the HVAC Performance Monitor Kit with Arduino Uno + NRF24?\",\n      \"acceptedAnswer\": {\n        \"@type\": \"Answer\",\n        \"text\": \"The HVAC Performance Monitor Kit with Arduino Uno + NRF24 includes all components needed: Arduino Uno R3, NRF24L01, DHT22, 16, I2C Backpack and more.
