This DHT11 is a sensor that combines both temperature and humidity sensing capabilities in a single package. It is not available as a standalone temperature-only or humidity-only sensor.
The temperature and humidity sensor DHT11 includes a built-in resistive humidity sensor and a thermistor for temperature measurement. These two sensing elements work together to provide temperature and humidity readings.
This sensor communicates with a microcontroller or other digital devices using a digital signal. It sends data in a serial format, where the microcontroller can read the temperature and humidity values from the sensor.
The DHT11 sensor module is widely used in various projects and applications, including weather stations, environmental monitoring systems, HVAC control, and other projects that require temperature and humidity measurements. It is known for its simplicity, low cost, and ease of use.
