MicroPython Driver for the Sensirion SHTC3 Temperature and Humidity Sensor

• Author(s): Bryan Siepert, Jose D. Montoya

class micropython_shtc3.shtc3.SHTC3(i2c, address: int = 0x70)[source]¶

Driver for the SHTC3 Sensor connected over I2C.

Parameters:¶

i2c : I2C¶

The I2C bus the SHTC3 is connected to.

address : int¶

The I2C device address. Defaults to 0x70

Raises:¶

RuntimeError – if the sensor is not found

Quickstart: Importing and using the device

Here is an example of using the SHTC3 class. First you will need to import the libraries to use the sensor

from machine import Pin, I2C
from micropython_shtc3 import shtc3

Once this is done you can define your machine.I2C object and define your sensor object

i2c = I2C(1, sda=Pin(2), scl=Pin(3))
sht = shtc3.SHTC3(i2c)

Now you have access to the attributes

temperature, relative_humidity = sht.measurements

property measurements : tuple[float, float]¶

Take sensor readings. Temperature and Relative Humidity

property operation_mode : str¶

Sensor operation_mode

Mode	Value
shtc3.SLEEP	0xB098
shtc3.WAKEUP	0x3517

property power_mode : str¶

Sensor power_mode

Mode	Value
shtc3.NORMAL	0x7866
shtc3.LOW_POWER	0x609C

property relative_humidity : float¶

The current relative humidity in % rH. This is a value from 0-100%.

property temperature : float¶

The current temperature in degrees Celsius
