hdc1080¶

MicroPython driver for the TI HDC1080 Temperature and Humidity sensor

• Author: Jose D. Montoya

class micropython_hdc1080.hdc1080.HDC1080(i2c, address: int = 0x40)[source]¶

Driver for the HDC1080 Sensor connected over I2C.

Parameters:¶

i2c : I2C¶

The I2C bus the HDC1080 is connected to.

address : int¶

The I2C device address. Defaults to 0x40

Raises:¶

RuntimeError – if the sensor is not found

Quickstart: Importing and using the device

Here is an example of using the HDC1080 class. First you will need to import the libraries to use the sensor

from machine import Pin, I2C
from micropython_hdc1080 import hdc1080

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))
hdc1080 = hdc1080.HDC1080(i2c)

Now you have access to the attributes

temp = hdc1080.temperature

property humidity_resolution : str¶

Sensor humidity_resolution

Mode	Value
hdc1080.HUM_RES_14BIT	0b00
hdc1080.HUM_RES_11BIT	0b01
hdc1080.HUM_RES_8BIT	0b10

property measurements : tuple[float, float]¶

Return Temperature in Celsius and Relative humidity in rh%

property operation_mode : str¶

Sensor operation_mode

Mode	Value
hdc1080.TEMP_AND_HUM	0b0
hdc1080.TEMP_OR_HUM	0b1

property relative_humidity : float¶

Relative Humidity in rh%

reset() → None[source]¶

Reset the sensor

property temperature : float¶

Temperature in Celsius

property temperature_resolution : str¶

Sensor temperature_resolution

Mode	Value
hdc1080.TEMP_RES_14BIT	0b0
hdc1080.TEMP_RES_11BIT	0b1
