EASY plug DS18B20 Temperature Sensor


The DS18B20 temperature sensor is exactly what it sounds like - a sensor used to measure ambient temperature.
The usable temperature ranges from -55°C to +125°C. It also supports multi-point mesh networking.

While there are many types of temperature sensors available in the market, the DS18B20 temperature sensor is the best choice in applications which require high accuracy and high reliability.
For electronic enthusiasts and hobbyists, the DS18B20 is a good start for learning and developing temperature-dependent prototypes.
This module should be used together with EASY plug control board.

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.

Test Code


What You Should See
Upload success, you should be able to see the Celsius and Fahrenheit value are printed out on the OLED screen.


  • OLED Not Lighting Up?

If upload the code successfully, but LED still not lights up. Make sure your board and OLED module are connected correctly.

  • Upload Failed ?

This happens sometimes, the most likely case is a confused Board and serial port, you should firstly select your proper board and port.
