# Demo of Rust on ESP32 (no RTOS) with MQTT and adafruit.io for temperature logging

## About

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

![Screenshot](./doc/screenshot.png "Screenshot")

It publishes the temperature value to the topic `/feeds/temperature`

## Setting Credentials

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

|---|---|

|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 ESP32 development board with the BMP180 connected and execute `cargo run --release`

Make sure to have the [Xtensa enabled Rust toolchain](https://github.com/esp-rs/rust-build) installed.
