Mastering the DHT11 Sensor with Arduino: Display Temp & Humidity on Serial Monitor!

Mastering the DHT11 Sensor with Arduino: Display Temp & Humidity on Serial Monitor! If you’ve ever wanted to turn your Arduino into a weather station (without the complicated forecast predictions), then today’s your lucky day! We’re diving into how to use the DHT11 temperature and humidity sensor with an Arduino. It’s simple, fun, and surprisingly useful for projects where you want to track the temperature or moisture level in the air. Ready to make your Arduino smarter? Let’s get started! What You’ll Need Before we jump into the code, let’s gather our gear. Here's what you’ll need: Arduino board (Any version works) DHT11 sensor (This is the star of the show) Jumper wires Breadboard (Optional, but highly recommended for neatness) Arduino IDE (Don’t forget to install it if you haven’t already!) Wiring the DHT11 Sensor Now, let’s talk about connections. The DHT11 has 4 pins, but we only need 3 for this project (I mean, who wants to overcomplicate things?). Here’s how you’ll wire it up: VCC (Pin 1) to 5V on your Arduino. GND (Pin 4) to GND on the Arduino. DATA (Pin 2) to any digital pin on your Arduino (we’ll use pin 7 in this example).
