DHT11 Temperature And Relative Humidity Sensor Module

The DHT11 is a basic, low-cost digital sensor used to measure temperature and humidity. It provides a calibrated digital output and is commonly used in DIY electronics projects, weather stations, and environmental monitoring systems. The sensor offers a temperature measurement range of 0-50°C with ±2°C accuracy and a humidity range of 20-90% with ±5% accuracy. The DHT11 operates on a single-wire communication protocol, making it easy to interface with microcontrollers and other digital systems. Despite its limitations in precision and response time, the DHT11 remains a popular choice for simple applications due to its affordability and ease of use.
