CircuitPython STTS22H Library¶

stts22h¶

CircuitPython Driver for the STTS22H Temperature Sensor

• Author(s): Jose D. Montoya

class stts22h.STTS22H(i2c_bus: busio.I2C, address: int = 0x3C)[source]¶

Driver for the STTS22H Sensor connected over I2C.

Parameters:¶

i2c_bus : I2C¶

The I2C bus the STTS22H is connected to.

address : int¶

The I2C device address. Defaults to 0x3C

Raises:¶

RuntimeError – if the sensor is not found

Quickstart: Importing and using the device

Here is an example of using the STTS22H class. First you will need to import the libraries to use the sensor

import board
import stts22h

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

i2c = board.I2C()  # uses board.SCL and board.SDA
stts = stts22h.STTS22H(i2c)

Now you have access to the attributes

temp = stts.temperature

property high_limit : bool¶

The bit is automatically reset to ‘0’ upon reading the STATUS register. :return: value if the temperature exceeds the high limit

property low_limit : bool¶

The bit is automatically reset to ‘0’ upon reading the STATUS register. :return: value if the temperature went under the low limit

property output_data_rate : str¶

Sensor output_data_rate

Mode	Value
stts22h.ODR_25_HZ	0b00
stts22h.ODR_50_HZ	0b01
stts22h.ODR_100_HZ	0b10
stts22h.ODR_200_HZ	0b11

property temperature : float¶

The temperature sensor in Celsius :return: Temperature

property temperature_high_limit : float¶

Temperature High Limit

property temperature_low_limit : float¶

Temperature Low limit
