Temperature and Humidity Sensor DHT11 + Resistor

Our Price: $4.00

Stock Status:In Stock

Product Code: SEN-1004

This is a low cost humidity and temperature sensor with a single wire digital interface. The sensor is calibrated and doesn't require extra components so you can get right to measuring relative humidity and temperature. The DHT11 outputs a calibrated digital signal. It utilizes exclusive digital-signal-collecting-technique and humidity sensing technology, assuring its reliability and stability.  Every sensor of this model is calibrated in accurate calibration chamber and the calibration-coefficient is saved in a type of OTP memory.

This sensor supports a sampling rate of about once every second.

   Operating range: humidity 20 to 90%RH, temperature 0 to 50℃
   Range of measuring humidity: 20% to 90%RH (0-50℃ temperature compensation)
   Range of measuring temperature: 0 to +50℃
   Accuracy of measuring humidity: ±5.0%RH
   Accuracy of measuring temperature: ±2.0℃
   Response time: <5s
   Supply Current:
   Mesurement: 0.5 to 2.5 mA
   Average: 0.2 to 0.5 mA
   Stand by: 100 to 150 uA

Included with this sensor is a 10K pullup resistor for the data pin to VCC.

Use the Arduino DHT library for easy sensor readings.  Rename this to "DHT" and place it on your sketch_dir/libraries/.
