Paper SHT30 Temperature & Humidity Sensor
Begin()
Description:
Initializes the SHT30 temperature and humidity sensor.
Syntax:
void Begin()
UpdateData()
Description:
Refreshes the measurement data.
- This API must be called to obtain new measurement values.
Syntax:
uint8_t UpdateData()
GetTemperature()
Description:
Reads the temperature measured by the SHT30 sensor.
Syntax:
float GetTemperature(TemperatureScale Degree = Cel)
GetRelHumidity()
Description:
Reads the humidity measured by the SHT30 sensor.
Syntax:
float GetRelHumidity()
