User Manual

Python and CircuitPython

It's easy to use the LPS33HW or LPS35HW sensors with Python and CircuitPython, and the Adafruit CircuitPython

LPS35HW (https://adafru.it/ERZ) module. This module allows you to easily write Python code that reads the pressure

and temperature and will work with either sensor.

You can use this sensor with any CircuitPython microcontroller board or with a computer that has GPIO and Python

thanks to Adafruit_Blinka, our CircuitPython-for-Python compatibility library (https://adafru.it/BSN).

CircuitPython Microcontroller Wiring

First wire up a LPS35HW or LPS33HW to your board for an I2C connection, exactly as shown below. Here's an

example of wiring a Feather M4 to the sensor with I2C:

Board 3V to sensor VIN (red wire)

Board GND to sensor GND (black

wire)

Board SCL to sensor SCL (yellow wire)

Board SDA to sensor SDA (blue wire)
