Description

DH11 Temperature & Humidity Sensor has excellent quality, fast response, anti-interference ability, low cost and other advantages. Single Wire serial interface that allows quick and easy system integration. Ultra-small size, low power consumption, signal transmission distance Up to 20 meters, making it to the class of applications and even the most demanding applications is the best choice.

DHT11 Temperature & Humidity Sensor Specifications

  • Supply voltage: 3.3 ~ 5.5V DC
  • Output: single-bus digital signal
  • Measuring range: Humidity 20-90% RH, Temperature 0 ~ 50 ℃
  • Accuracy: Humidity + -5% RH, temperature + -2 ℃
  • Resolution: Humidity 1% RH, temperature 1 ℃
  • Long-term stability: <± 1% RH / Year

Notes

  1. to avoid the use of the condensation conditions
  2. long-term storage temperature 10-40 ℃, humidity below 60%
  3. the use of power and ground connection to be correct, so as not to damage the sensor
