Our newest project and demo!
A data logging system for temperature and humidity with the ability to see hourly, weekly, monthly data points.
Using the Arduino Nano, Matrix Orbital GTT35A I2C TFT, DHT22 Temperature & Humidity Sensor, GTT HMI GUI Designer
About this project
This project demonstrates how easy it is to create a simple display panel (for a thermostat) by interfacing Matrix Orbital GTT Intelligent TFT HMI display with an Arduino Nano via I2C. A DHT22 temperature and humidity sensor is used to obtain temperature and humidity information. This information is processed by the Arduino Nano to display hourly, 24-hour, and weekly historical charts. A live chart is also available for viewing of the current temperature and humidity.
Adding in some electrical and/or electromechanical systems behind this display panel can turn this unit into a thermostat with a beautiful full colour TFT display.
