The DHT11 is a widely used sensor for measuring temperature and humidity. Its simplicity and affordability make it a favorite for weather stations, home automation, and IoT projects.
How Does It Work?
The DHT11 uses a capacitive humidity sensor and a thermistor to measure the surrounding air. It sends digital signals to a microcontroller, making it easy to read data.
Why Choose the DHT11?
- Compatible: Works seamlessly with Arduino, Raspberry Pi, and ESP32.
- Compact: Small and easy to integrate into projects.
- Precise Enough: Measures temperatures between 0°C to 50°C and humidity from 20% to 90%.
- Low Power: Perfect for battery-operated devices.
