The DHT11 sensor is a basic, low-cost sensor that provides reliable temperature and humidity readings in digital form. It is widely used in embedded systems, IoT projects, and various other applications that require monitoring of environmental conditions. The sensor’s operating range for temperature is 0°C to 50°C with an accuracy of ±2°C, and for humidity, it is between 20% to 90% with an accuracy of ±5% RH. It communicates via a single-wire interface, making it easy to integrate with microcontrollers like Arduino and Raspberry Pi.

    Despite its affordable price, the DHT11 is reliable enough for general monitoring purposes, although it is less accurate than its more expensive counterparts, such as the DHT22 or AM2302. Still, its performance is more than adequate for many simple applications in smart home automation, weather stations, and basic robotics.
