Description
Description
The DHT11 is a low-cost digital temperature and humidity sensor designed for basic environmental monitoring applications. It integrates a capacitive humidity sensor and a thermistor to provide calibrated digital output through a single data pin. Operating at 5 V, it eliminates the need for analog inputs and simplifies system integration. The sensor updates readings every 2 seconds, ensuring stable and reliable measurements for non-time-critical applications. It is well suited for educational projects, microcontroller experiments, and simple weather monitoring systems.
