bjoernQ/esp32c3-rust-std-temperature-logger: MQTT temperature logger running on ESP32C3 in Rust (std)

Demo of Rust on ESP32C3 (using ESP-IDF) with MQTT and adafruit.io for temperature logging

This will read the temperature from a connected BMP180 sensor via I2C and send it via MQTT to adafruit.io every five minutes.

You need to set these environment variables for a successful build.

Name Value SSID SSID of your WiFi access point PASSWORD Your WiFi password ADAFRUIT_IO_USERNAME Your adafruit.io username ADAFRUIT_IO_KEY Your adafruit.io API key

To run the application connect your ESP32C3 development board with the BMP180 connected and execute cargo run
