Description: 1. Features: DHT11 is a low-cost digital temperature and humidity sensor module. Each pack includes 25 individually sealed sensors for protecting against moisture and contamination. 2. Measurements: The sensor accurately measures temperatures from -40°C to +80°C (F: -40°F to 176°F) and relative humidity levels from 0% to 100%. 3. Easy Connection: DHT11 features a simple data transmission protocol, making it easy to connect the module to microcontrollers or other systems for reading temperature and humidity data. 4. Data Output: The sensor outputs data in digital format as a 40-bit string through four wires – VCC (5V power), GND (ground), Data, and SDA (Serial Data Line). 5. Signal Stability: DHT11 has improved signal stability over the DHT08, making it suitable for applications where precise readings are required. 6. Calibration: The sensor doesn't need calibration for temperature, but humidity may require adjustments depending on the application and environment. 7. Power Consum
