Dht22 Projects

Build an environmental weather station with the Raspberry Pi Pico W. Acquire temperature and humidity metrics from a digital DHT22 sensor, render a real-time 128x64 dashboard on an SSD1306 OLED display, and stream JSON telemetry.

Construct a multi-zone environmental safety telemetry hub using the Arduino Mega 2560. Reads temperature, humidity, and ambient light across multiple rooms and displays real-time safety metrics on a large 20x4 I2C LCD screen.

Build a small color weather dashboard with an Arduino Uno, a DHT22 temperature and humidity sensor, and an ILI9341 TFT display. The Arduino reads the room conditions, draws separate dashboard cards, and uses color to show whether the room feels cool, comfortable, warm, dry, or humid.

Build an automated greenhouse climate controller using a DHT22 sensor, I2C LCD1602 display, simulated cooling ventilation fan, and heating elements.
