Here's a feature of the DHT11 sensor :

Combined Sensor: The DHT11 integrates a temperature sensor and a humidity sensor within a single module. This allows it to measure both temperature and relative humidity simultaneously.

Digital Output: The sensor provides a digital output signal, making it easy to interface with microcontrollers and digital devices. The output signal is in the form of a time-based digital signal that reflects the temperature and humidity readings.

Wide Operating Range: The DHT11 can measure temperature in the range of 0°C to 50°C (32°F to 122°F) with an accuracy of ±2°C. For humidity, it can measure in the range of 20% to 90% RH with an accuracy of ±5%.

Simple Interface: The sensor communicates using a single-wire digital protocol. It requires minimal external components for interfacing, making it easy to integrate into projects.

Low Power Consumption: The DHT11 sensor operates on low power, making it suitable for battery-powered applications.

Factory Calibrated: The sensor is factory-calibrated, which means it should provide reasonable accuracy without the need for user calibration.
