DHT-11 Digital Temperature And Humidity Sensor

The DHT-11 Digital Temperature and Humidity Sensor is a basic, ultra low-cost sensor for measuring temperature and humidity. It utilizes a capacitive humidity sensor and a thermistor to assess the surrounding air, outputting a digital signal on the data pin, which eliminates the need for analog input pins.

Features:

• Digital Output: Outputs a digital signal, making it easy to interface with microcontrollers.
• Ease of Use: Simple to use, though it requires precise timing to retrieve data.
• Measurement Interval: Can only provide new data every 2 seconds, so ensure your code reads the sensor at intervals of 2 seconds or longer.

Comparisons:

• Accuracy: Less precise and accurate than the DHT22.
• Range: Operates within a smaller range of temperature and humidity compared to the DHT22.

Advantages:

• Size and Cost: Smaller and less expensive than the DHT22, making it ideal for cost-sensitive applications.

Despite its limitations in precision and range compared to the DHT22, the DHT-11 remains a compact and affordable option for basic temperature and humidity measurement needs.
