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.
