Product Description
The DHT11 Digital Temperature and Humidity Sensor is a low-cost and easy-to-use sensor designed for measuring temperature and relative humidity in electronics, Arduino, IoT, and embedded projects. It uses a capacitive humidity sensing element and thermistor to provide calibrated digital readings through a single data pin.
The sensor provides a digital output, eliminating the need for a separate analog input. Its simple interface makes it suitable for beginners, students, hobbyists, and various environmental monitoring applications.
The DHT11 features low power consumption, built-in calibration, long-term stability, and reliable digital signal transmission. For accurate operation, it is recommended to maintain a minimum reading interval of approximately 2 seconds, as the sensor updates its measurements at this rate.
Compared with the DHT22, the DHT11 offers a narrower measurement range and lower accuracy, but its compact size, simplicity, and economical price make it a practical choice for basic temperature and humidity monitoring.
