DHT11 Temperature Sensor

DHT11 Temperature Sensor The DHT11 is a low-cost digital sensor used to measure temperature and relative humidity. It contains a temperature-sensing element and a humidity-sensing element with a built-in digital signal processor. The sensor provides calibrated digital data through a single data pin, making it easy to interface with Arduino, ESP32, and other microcontrollers. Key features: Temperature range: 0°C to 50°C Temperature accuracy: approximately ±2°C Humidity range: 20%–80% RH Humidity accuracy: approximately ±5% RH Operating voltage: 3.0–5.5 V Digital output: Single-wire communication Low cost and easy to use In an environmental monitoring project, the DHT11 can be used to measure the temperature and humidity of the surrounding environment and display the readings on an OLED/LCD or send them to a monitoring system.
