Keyestudio EASY plug DHT11 Temperature and Humidity Sensor

Introduction

The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor.
It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and provides a pre-calibrated digital signal output.
This DHT11 sensor has fast response, anti-interference ability, excellent reliability and long term stability.

Special Note:
The sensor/module is equipped with the RJ11 6P6C interface, compatible with our keyestudio EASY plug Control Board with RJ11 6P6C interface.
If you have the control board of other brands, it is also equipped with the RJ11 6P6C interface but has different internal line sequence, can’t be used compatibly with our sensor/module.

Specification

  • Connector: Easy plug
  • Supply Voltage: 5V
  • Relative Humidity and temperature measurement
  • Good for 20-90% humidity readings with 5% accuracy
  • Good for 0-50°C temperature readings ±2°C accuracy
  • Interface: Digital
  • Low Cost


Technical Details

  • Dimensions: 42mm*20mm*18mm
  • Weight: 5.6g
