Hemera Indoor Sensor Node

=========================

Hemera is an indoor wireless sensor node that measures temperature, humidity, light and motion.

The node contains three key sensors:

- Sensirion SHT11 (Temperature and Humidity)

- Rohm BH1721 (Light)

- PIR (Motion)

Setup

-----

### 1) Clone & install the Lab11 version of tinyos-main:

    git clone https://github.com/lab11/tinyos-main.git

    cd tinyos-main/tools

    ./Bootstrap

    ./configure

    make

    sudo make install

### 2) Clone yours truly:

    git clone https://github.com/lab11/hemera.git

### 3) Add to `bash.rc`:

    export TINYOS_ROOT_DIR=/tinyos-main

    export TINYOS_ROOT_DIR_ADDITIONAL=/hemera/tinyos:$TINYOS_ROOT_DIR_ADDITIONAL

### 4) Set up the RaspberryPi (optional, but recommended):

A modified RaspberryPi can be utilized to receive and forward data to GATD. 

If you choose to use one, you need the [Linux CC2520 Driver](https://github.com/ab500/linux-cc2520-driver) for the RPi.

Instead of installing this manually, it is suggested to download & install the preinstalled image from [this torrent](https://github.com/lab11/raspberrypi-cc2520/tree/master/torrents).

Go to https://github.com/lab11/raspberrypi-cc2520 for additional details on setup.

Clone the RPi repo:

    git clone https://github.com/lab11/raspberrypi-cc2520.git

Add to `bash.rc`:

    export TINYOS_ROOT_DIR_ADDITIONAL=/raspberrypi-cc2520/tinyos:$TINYOS_ROOT_DIR_ADDITIONAL

### 5) Get the compilers

In order to compile the TinyOS code you need the msp430 and the ARM compilers

Sense Stuff

-----------

After you have finsihed the above setup, you should be ready to install apps on the Hemera board.

The basic sense & broadcast app is HemeraAM. To install it, go to `/hemera/tinyos/apps/HemeraAM` and follow the README. 

To receive & forward data to GATD on the RPi, go to `/hemera/tinyos/apps/RpiGatdForwarder` and follow the README.
