Wemos SHT30 readings on an OLED example

Another example of connecting Wemos shields and modules together, this time we will use an SHT30 shield instead of the DHT shield we used in a previous example

Wemos Dual Base shield – a basic shield for connecting other shields and modules

Wemos D1 Mini : the basic ESP8266 module – there are 3 variants of this board

Wemos OLED shield : a 64×48 I2C OLED display which can display a few lines of text

Wemos SHT30 shield : an I2C digital temperature and humidity sensor based on the SHT30

Code

2 libraries needed for this example again

[codesyntax lang=”cpp”]

#include <Wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>
#include <WEMOS_SHT3X.h>

#define OLED_RESET 0  // GPIO0
Adafruit_SSD1306 display(OLED_RESET);

SHT3X sht30(0x45);

void setup() 
{
  display.begin(SSD1306_SWITCHCAPVCC, 0x3C);
}

void loop() {
  
  // Clear the buffer.
  display.clearDisplay();
  display.setTextSize(1);
  display.setCursor(0, 0);
  display.setTextColor(WHITE);

  if(sht30.get()==0)
  {
    display.println("T: ");
    display.println(sht30.cTemp);
    display.println("H: ");
    display.println(sht30.humidity);
  }
  else
  {
    display.println("Error!");
  }
  display.display();
  delay(1000);
}

Run this example and you will see the temperature and humidity displayed on the OLED display
