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


Connect It Up

Connect the EASY Plug DHT11 sensor to control board using an RJ11 cable. Then connect the control board to your PC with a USB cable.

Upload the Code

Below is an example code. Open or drag below code to Mixly Blocks and upload.

thumb


What You Should See

Open the Serial monitor, you should be able to see the temperature and humidity data.

thumb


Little Knowledge:

  • If the data is scrolling very fast, you can’t make out the data clearly, so you can modify the Delay time in the code to check it easily.
