  • Data/Clock -PinNum: Assigns which digital I/O line is used for each SPI line. Value passed is 0-7 corresponding to FIO0-FIO7.
  • StatusReg: Returns a read of the SHT1X status register.
  • Temperature: Returns the raw binary temperature reading.
  • Humidity: Returns the raw binary humidity reading.
  • #CRC: Returns the CRC values from the sensor.
