Temperature & Humidity

The DHT11 sensor allows your projects to measure ambient temperature and humidity.
It is one of the most commonly used sensors in DIY electronics and IoT, helping students connect code with real-world environmental data.

What It Does

This example reads the current humidity from the DHT11 sensor and displays the values.
It gives you a simple way to monitor your surroundings and respond to changes in the environment.

Real-World Applications

Temperature and humidity monitoring is an essential part of many real-life systems, such as:

  • 🏠 Smart Homes – Automating fans, air conditioners, and humidifiers.
  • 🌱 Smart Agriculture – Monitoring greenhouse or soil conditions to protect crops.
  • 🌍 Weather Stations – Collecting local climate data for learning or prediction.
  • 🏥 Health & Safety – Ensuring comfortable and safe indoor environments.
  • 📦 Logistics & Storage – Monitoring warehouses for sensitive goods like food or medicine.

By using the DHT11, students learn how data from the environment can trigger real-world actions and innovations.

✅ With the DHT11 sensor, students can build projects that sense, respond, and adapt to environmental conditions, making their prototypes more intelligent and practical.
