Product Details
DHT11 Digital Temperature and Humidity Sensor Module
The DHT11 Sensor Module is a cost-effective and reliable solution for obtaining accurate, pre-calibrated digital measurements of ambient temperature and relative humidity. The module version simplifies integration by including the necessary pull-up resistor and filtering capacitor on a small PCB, offering a straightforward 3-pin interface for fast connection to any microcontroller like Arduino or Raspberry Pi.
🔧 Key Features
- High Reliability: Uses a resistive-type humidity component and an NTC thermistor.
- Digital Output: Sends data via a single-wire serial interface, requiring only one I/O pin.
- Wide Voltage Range: Operates stably on 3.3V to 5.5V DC supply.
- Low Power: Very low current consumption, making it perfect for power-sensitive applications.
- Accuracy: Provides reliable readings with $\pm 2^\circ\text{C}$ temperature and $\pm 5\% \text{ RH}$ humidity accuracy.
- Factory Calibrated: No complex calibration routines are needed by the end-user.
💡 Applications
- Essential component for Home Weather Stations and environmental monitoring.
- Used in HVAC, Humidifier, and Dehumidifier control systems.
- Perfect for Greenhouse and Smart Agriculture projects for climate control.
- Ideal for Educational and DIY electronics projects due to its simple interface.
