# Nerves Thermal Camera

This project is an Elixir Nerves firmware that implements a thermal camera using

the Melexis MLX90640 sensor. It is tested on a Raspberry Pi Zero W, but it

should work on other WiFi-enabled Raspberri Pi models too.

Other platforms supported by Nerves _should_ work too, but may need

modifications.

# Build and installation

The pre-requisite is that you have installed the [Elixir

language](https://elixir-lang.org), [Nerves](https://nerves-project.org), and

[Node.js](https://nodejs.org/en/). You can find installation guides on their

respective websites.

Then:

  1. Clone or download the repository and open your terminal

  2. `cd` into the project directory and set the following environment variables:

     ```bash

     export MIX_TARGET=rpi0 # (or another Nerves target like `rpi3`)

     export MIX_ENV=prod

     # In the following two commands, replace `your_ssid` with your WiFi SSID

     # and `your_psk` with your WiFi password

     export THERMALCAM_SSID=your_ssid

     export THERMALCAM_PSK=your_psk

     ```

     Optionally, you can also set these environment variables:

     `THERMALCAM_NET_REG_DOMAIN` for the regulatory domain of the network

     (default to `DE`), and `THERMALCAM_KEY_MGMT` for the key management

     (default to `wpa_psk`).

  3. Run `make firmware` to build the firmware

  4. Insert the SD card in your computer and, from the same terminal window as

     before, run `make firmware.burn` to burn the firmware on the SD card.

The SD card should now be ready.

# Usage

  1. Follow the instructions above to burn a firmware image on the SD card

  2. Wire the MLX90640 to the Raspberry Pi

  3. Turn on the Raspberry Pi and wait for it to connect to the WiFi network

  4. From another device (computer or smartphone) connected to the same WiFi,
