dht11 datasheet pdf - This DFRobot DHT11 Temperature & Humidity Sensor features a temperature & humidity sensor complex with a calibrated digital signal output.
By using the exclusive digital-signal-acquisition technique and temperature & humidity sensing technology, it ensures high reliability and excellent long-term stability.
This sensor includes a resistive-type humidity measurement component and an NTC temperature measurement component, and connects to a highperformance 8-bit microcontroller, offering excellent quality, fast response, anti-interference ability and cost-effectiveness.
Each DHT11 element is strictly calibrated in the laboratory that is extremely accurate on humidity calibration. The calibration coefficients are stored as programmes in the OTP memory, which are used by the sensor’s internal signal detecting process.
The single-wire serial interface makes system integration quick and easy. Its small size, low power consumption and up-to-20 meter signal transmission making it the best choice for various applications, including those most demanding ones. The component is 4-pin single row pin package. It is convenient to connect and special packages can be provided according to users’ request.
Its fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds.

I talk a little about how the humidity sensor works, and how to set it up to output readings to the Arduino serial monitor or a 16x2 LCD display. Then I show you how to modify the program to output Celsius or Fahrenheit.

DHT11 - Humidity and Temperature Sensor
The DHT11 is a basic, low-cost digitaltemperature and humidity sensor. It uses a capacitive humidity sensor and a thermistorto measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed).Its fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds.
Features of DHT11
