About this product
A beginner kit for building a small weather station. A DHT11 sensor measures temperature and humidity, and an Arduino Uno shows the readings every two seconds on a 0.91-inch I2C OLED display. Assembly is solderless on a breadboard, and a DHT22 sensor can be used instead for better accuracy.

Frequently asked questions
Can I switch from DHT11 to DHT22?
Yes. Install the DHT library and change the sensor line in the code to DHT dht(2, DHT22);. The wiring on pin 2 stays the same because both sensors use the same three-pin layout.
How do I connect the OLED display?
Connect SDA to pin A4 and SCL to pin A5 on the Arduino Uno, then connect the display power and GND pins as shown in the kit guide. The I2C interface needs only these two data wires.
