The DHT11 Temperature and Humidity Sensor Module is a reliable and easy-to-use sensor for monitoring environmental conditions. The module's humidity measurement range is 20% to 90%RH, and temperature range is 0°C to 60°C, with ±5%RH and ±2°C error margins for accurate measurement data. The module is suitable for many hobby, DIY and IoT applications. The sensor is powered by 5V power supply and the digital signals are easily interfaced with Arduino, Raspberry Pi and other microcontrollers. Its small size (28×12×8mm) and pre-drilled mounting hole allow for quick and easy installation, and its high reliability and stability over time make it a reliable option for ongoing monitoring
