API

SHT30

class hardware.sht30.SHT30

Bases: SHT30

class driver.sht30.SHT30(i2c=None, delta_temp=0, delta_hum=0, i2c_address=68)

Bases: object

Create a SHT30 object.

Parameters:

• i2c (I2C) – The I2C bus object.

• delta_temp (int) – The temperature delta to apply to measurements.

• delta_hum (int) – The humidity delta to apply to measurements.

• i2c_address (int) – The I2C address of the sensor.
