What is a DHT11 sensor?

The DHT11 sensor is a basic, low-cost digital temperature and humidity sensor often used in electronics projects. It provides reliable readings of temperature in Celsius and humidity in percentage, operating within a range of 0-50°C for temperature and 20-80% for humidity. The sensor communicates using a single-wire protocol, making it easy to interface with microcontrollers like Arduino and Raspberry Pi. Its simplicity and affordability make it popular for hobbyist and educational applications.
