This is DHT11 sensor for measuring temperature and humidity. It is accurate and inexpensive sensor that includes an ADC to convert analog values of humidity and temperature. 8-bit microcontroller in the sensor is used for data conversion.
It provides reliable output results when the ambient humidity in the range from 20% RH to 90% RH, and a temperature range of 0 ° C to 50 ° C. It covering the needs of most home and everyday application conditions.
Power supply: 3.3-5V
Current: 2.5mA max use of current during conversion (when data request)
