Create an object, wlan, which is then used to connect to your Wi-Fi access point. import networkįrom breakout_bme68x import BreakoutBME68X, STATUS_HEATER_STABLEģ.

Import five modules of Python code for Wi-Fi connectivity, controlling the pace of the code, accessing the BME688 sensor, I2C and MQTT. upip.install(‘umqtt.simple’) Publishing Sensor Data to MQTTĢ. This module is a simplified MQTT client for MicroPython. The upip module is a version of the Python package manager, pip, for MicroPython. Remember to press Enter at the end of each line. Change the Wi-Fi AP and PASSWORD to match those of your Wi-Fi access point. Open Thonny and in the Python shell write four lines of MicroPython to connect your Raspberry Pi Pico W to Wi-Fi. If you have not installed Thonny, please also follow those instructions.ģ. Later instructions show how to install Thonny on your machine. Follow steps 2 and 3 in these instructions to flash the Pimoroni firmware to your Raspberry Pi Pico W. This firmware comes with a MicroPython module for the BME688 sensor.Ģ.

Download the latest Pimoroni MicroPython firmware for the Raspberry Pi Pico W. We will be using both, to illustrate the portability of the code.ġ. For this project you can use a Raspberry Pi Pico W, or Pimoroni’s new Enviro Indoor kit.
