🔢 Code

Below is the Basic example. It can be found in File > Examples > Microfire_Mod-NTC > Basic in the Arduino IDE.

#include "Microfire_SHT3x.h"
Microfire::SHT3x sht30;

void setup() {
  Serial.begin(9600);
  Wire.begin();
  sht30.begin();
}

void loop() {
  sht30.measure();
  Serial.println((String)sht30.tempC + " °C");
  delay(1000);
}

Typing python3 -m Microfire_SHT3x.shell will start the shell application and give access to the sensor. Type help to see a listing of the commands available

2.

🔢 Code

Create a python script and run the following sample code.

from Microfire_SHT3x import Microfire_SHT3x
sht30 = Microfire_SHT3x()
sht30.begin()
sht30.measure()
if sht30.status:
  print("Error: " + sht30.status_string[sht30.status])
else:
  print(str("{:.3f}".format(sht30.tempC)) + "°C")
  print(str("{:.3f}".format(sht30.tempF)) + "°F")
  print(str("{:.3f}".format(sht30.vpd_kPa)) + " VPD kPa")
  print(str("{:.3f}".format(sht30.dew_pointC)) + " dew point °C")
  print(str("{:.3f}".format(sht30.dew_pointF)) + " dew point °F")
  print(str("{:.3f}".format(sht30.RH)) + " %RH")
