DHT11 Humidity & Temperature Sensor

DHT11 Temperature and Humidity Sensor

The DHT11 is a low-cost digital sensor for measuring ambient temperature and relative humidity. It provides a calibrated digital signal and is commonly used with Arduino and other microcontrollers in basic environmental monitoring projects.

Key Specifications

• Supply voltage: 3V to 5.5V DC
• Digital signal output
• Typical humidity range: 20% to 90% RH
• Typical temperature range: 0°C to 50°C
• Humidity accuracy: Approximately ±5% RH
• Temperature accuracy: Approximately ±2°C

Common Applications

• Weather stations and room monitors
• Incubator and greenhouse prototypes
• Home automation and ventilation projects
• Arduino learning and sensor experiments

For stable readings, follow the recommended sampling interval and wiring requirements for the DHT11.

For a basic room-monitoring project, connect the DHT11 to an Arduino UNO R3 and follow the sensor library wiring and sampling guidance.
