What we need is a Wemos D1 Mini board, which can be found on Aliexpress for around 5$. And of course the SHT30 shield can also be found on Aliexpress for a few dollars.<\/p>\n

SHT30 @ Aliexpress<\/a><\/p>\n

Wemos D1 Mini @ Aliexpress<\/a><\/p>\n

Code:<\/strong><\/p>\n

Next up is installing the Arduino Library<\/a> for the SHT30, unzip in libraries folder and restart Arduino IDE.<\/p>\n

Then in Arduino IDE select the example called SHT30_SHIELD, or use example code below,\u00a0 just to verify that our sensor is working correctly.<\/p>\n

[codesyntax lang=”c” lines=”no” title=”Basic Example”]<\/p>\n

#include <WEMOS_SHT3X.h>\r\n\r\nSHT3X sht30(0x45);\r\n\r\nvoid setup() {\r\n\r\n  Serial.begin(115200);\r\n\r\n}\r\n\r\nvoid loop() {\r\n\r\n  if(sht30.get()==0){\r\n    Serial.print(\"Temperature in Celsius : \");\r\n    Serial.println(sht30.cTemp);\r\n    Serial.print(\"Temperature in Fahrenheit : \");\r\n    Serial.println(sht30.fTemp);\r\n    Serial.print(\"Relative Humidity : \");\r\n    Serial.println(sht30.humidity);\r\n    Serial.println();\r\n  }\r\n  else\r\n  {\r\n    Serial.println(\"Error!\");\r\n  }\r\n  delay(1000);\r\n\r\n}<\/pre>\n
[\/codesyntax]<\/p>\n
Then open up the serial monitor and you should see it reporting temperature and humidity:<\/p>\n

Thats it! Now play around with it. Hope this short guide was helpful.<\/p>\n","protected":false},"excerpt":{"rendered":"
