ARDUINO - SPFD5408 TFT LCD 2.4 TEMP and HUMIDiTY Monitor. Fahrenheit & Celsius!

Hello world! Today i made a Temp & Humidity Monitor with a DHT11 Sensor & the 2.4 TFT LCD Shield on a arduino Mega. Its shows Fahrenheit & celsius, Also for both Heat Indexes are displayed.

Follow the next step for the Code, Schematic, Libraries & Parts list.

You need 3 Libraries. They are included in the downloads.

• SPFD5408_Adafruit_GFX.h
• SPFD5408_Adafruit_TFTLCD.h
• SPFD5408_TouchScreen.h

Step 1: Schematic, Code, Libraries & Parts List.

Just wire the DHT11 Like the Schematic shows, and plug on the TFT LCD on top of the Arduino Mega.

Make sure you download and install the libraries, and Upload the code and you have yourself a nice cheap

to build Temp & Humidity monitor.

Parts list:

• Arduino Mega
• 2.4 TFT LCD SPFD5408 (Aliexpress got them very cheap)
• DHT11 Temperature sensor. KY-015
• Jumper wires

Good luck! Follow me for more!

For MCUFRIEND TFT LCD Replace the first 8 lines with

#include <Adafruit_GFX.h>// Core graphics library

#if defined(_GFXFONT_H_)

#include <Fonts/FreeSans9pt7b.h>

#define ADJ_BASELINE 11 //new fonts setCursor to bottom of letter

#else

#define ADJ_BASELINE 0 //legacy setCursor to top of letter

#endif

#include <MCUFRIEND_kbv.h>

MCUFRIEND_kbv tft;

And replace

tft.begin(0x7783); //MCUFRIEND Chipset ID on Librarytft.begin(0x7783);

Could you, please, share the code to use with MCUFriend?
And what libraries are you using?

Ive tried to follow your instructions, but is not working for me

Thanks a lot
