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.
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.
What You Should See
Open the Serial monitor, you should be able to see the temperature and humidity data.
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.
Extension Experiment
Make a Hygrothermograph
Hookup Guide
Connect the EASY Plug DHT11 sensor and 1602 LCD module to control board using RJ11 cables.
Test Code
Below is an example code.
What You Should See
Upload success, you should be able to see the temperature and humidity data are showed on the LCD screen.
