• Author(s): Jose D. Montoya

class micropython_mmr902.mmr902.MMR902(i2c, address: int = 0x65)[source]¶

Driver for the MMR902 Sensor connected over I2C.

Parameters:¶

i2c : I2C¶

The I2C bus the MMR902 is connected to.

address : int¶

The I2C device address. Defaults to 0x65

Raises:¶

RuntimeError – if the sensor is not found

Quickstart: Importing and using the device

Here is an example of using the MMR902 class. First you will need to import the libraries to use the sensor

from machine import Pin, I2C
from micropython_mmr902 import mmr902

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))
mmr = mmr902.MMR902(i2c)

Now you have access to the attributes

temp = mmr.temperature

property operation_mode : str¶

Sensor operation_mode

Mode	Value
mmr902.MODE1	0XA0
mmr902.MODE2	0XA2
mmr902.MODE3	0XA4
mmr902.MODE4	0XA6

property pressure : float¶

Pressure in mmHg

property temperature : float¶

Temperature in Celsius
