DHT11 Temperature and Humidity Sensor with an E-Ink Display Module

Posted by AlexChu, 16/09/2017

Quickly and easily display your air’s temperature and humidity with a DHT11 sensor and an E-ink display module. This method will have an update on a 5 second loop so you get updated results continuously. Once you unplug the module, the last update will remain on the screen until you change the code or re-plug the display so it can update again (everlasting e-ink!)
Ready to get started?
What you’ll need:
Hardware

Firmware

Note: For this project, you do not need the DHT11 library as we’ll provide the code, but we recommend you download it for future use

Here’s what to connect:

DHT11Arduino Uno
GNDGND
VCCVCC
DataA0
E-ink Display 
GNDGND (either is fine)
SDAD11
SCLD13
CS1D6
D/CD5
3.3V3.3V (5V is also fine)
BS1D8
BU/BusyD7
RESRESET

Once you’re connected, run this code.

And that’s how you get your temperature and humidity data displayed in E-ink. How about we try OLED next!
