DHT11 is an inexpensive sensor that provides calibrated digital outputs for ambient temperature and relative humidity. It comes in a single row 4-pin package and operates from 3 to 5.5V power supply. It can measure temperature from 0-50 °C with an accuracy of ±2°C and relative humidity ranging from 20-95% with an accuracy of ±5%. It has got its own proprietary 1-wire protocol, and therefore, the communication between the sensor and a microcontroller is not possible through a direct interface with any of its peripherals. The protocol must be implemented in the firmware of the MCU through bit-banging of an I/O pin.

Low-cost temperature and humidity sensor. Requires a single digital I/O pin to read both temperature and humidity values. Details:

  • Operating voltage: 3-5V;
  • Humidity: 20%-80%, 5% accuracy;
  • Temperature: 0° to 50°C, ±2°C accuracy.
