ESP32 + BME280 sensor

Written in MicroPython. Reads temperature, humidity and barometric pressure. Sends it to a MQTT broker. InfluxDB will be added soon.

Installation

  • Download MicroPython here
  • Then flash it to your microcontroller, ESP32 for example:
esptool.py -p /dev/ttyACM0 erase_flash
esptool.py -p /dev/ttyACM0 --baud 460800 write_flash 0 ESP32_GENERIC_C3-20250911-v1.26.1.bin

Use Thonny (graphical IDE) or ampy (CLI) to flash the files to the microcontroller.

Example with ampy:

ampy --port /dev/ttyACM0 put config.py
ampy --port /dev/ttyACM0 put bme280_float.py
ampy --port /dev/ttyACM0 put main.py
