DHT11 Temperature and Humidity Sensor Module

The DHT11 Temperature and Humidity Sensor Module is a basic, low-cost digital temperature and humidity sensor. It provides calibrated digital output via a single-wire interface, making it ideal for beginners and simple weather stations.

Key Features

• Measures temperature and humidity in one module
• Digital output via single-wire interface
• Factory calibrated for stable readings
• Low power consumption suitable for battery projects
• Compact module with onboard components
• 3-5V operation compatible with Arduino and ESP
• No additional components needed

Technical Specifications

Applications

• Basic weather stations and temperature monitoring
• Home automation climate control
• Agriculture monitoring and greenhouse control
• Environmental sensing projects
• HVAC system feedback
• Educational STEM projects and learning

Important Notes

• Requires 1-second minimum between readings
• Lower accuracy than DHT22 – consider upgrading if precision needed
• Use DHT library (Adafruit or simpleDHT) for Arduino
• Pull-up resistor (4.7K-10K) may be needed on data pin
• Not suitable for freezing or very high-temperature environments
