The KY-015 3pin DHT11 digital temperature and relative humidity sensor module is a device used to measure and report both temperature and relative humidity. It consists of a DHT11 sensor, which is a type of temperature and humidity sensor, and an associated circuit board or module that provides the necessary electrical connections and processing circuitry.

The DHT11 sensor uses a combination of temperature-sensitive and humidity-sensitive components to measure both temperature and relative humidity. It is commonly used in a variety of applications, such as weather stations, environmental monitoring systems, and HVAC (heating, ventilation, and air conditioning) systems.

The KY-015 3pin DHT11 sensor module typically includes a 3-pin connector or interface for connecting to a microcontroller or other device, as well as any necessary processing or control circuitry. It may also include additional features such as a display or user interface for reading and displaying the measured temperature and humidity data.
