This is a DHT11 sensor for measuring temperature and relative humidity. It is an accurate and inexpensive sensor that includes an analog-to-digital converter (ADC) to convert analog values of relative humidity and temperature.
The 8-bit microcontroller in the sensor is used for data conversion.
It provides a reliable output at ambient humidity in the range of 20% RH to 90% RH and temperature in the range of 0 ° C to 50 ° C. It is suitable for most home/office measurements and everyday applications.
