DHT11 Temperature and Humidity Sensor with an E-Ink Display Module
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
- E Ink Display module
- DHT11 Sensor
- Arduino Uno
- 2 x Bread board
- Dupont wire
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:
DHT11 | Arduino Uno |
GND | GND |
VCC | VCC |
Data | A0 |
E-ink Display | |
GND | GND (either is fine) |
SDA | D11 |
SCL | D13 |
CS1 | D6 |
D/C | D5 |
3.3V | 3.3V (5V is also fine) |
BS1 | D8 |
BU/Busy | D7 |
RES | RESET |
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!
