摘要

The DHT11 humidity and temperature sensor is an economical peripheral manufactured by D-Robotics UK (www.droboticsonline.com). It is capable of measuring relative humidity between 20 and 90% RH within the operating temperature range of 0 to 50°C with an accuracy of ±5% RH. Temperature is also measured in the range of 0 to 50°C with an accuracy of ±2°C. Both values are returned with 8-bit resolution.
