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

Pi-to-Cloudgate-Sensor

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

This is an example python script that reads sensor data from a Raspberry Pi's GpIO and prints it to serial as a JSON object. By default this script is to be used with a CloudGate and is configured to print to the following serial port:

```

/dev/serial/by-id/usb-Prolific_Technology_Inc._USB-Serial_Controller-if00-port0

```

Dependencies

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

This assumes you are using raspbian 

* Raspbian OS running in your Raspberry Pi.

* Python >2.7 (sudo apt-get install python-dev)

* Adafruit's DHT-sensor-library (https://github.com/adafruit/DHT-sensor-library)

* RPi modules (sudo apt-get install python-rpi.gpio)

Wiring up the Raspbery Pi

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

This script takes input from:

* Pin 17: A DHT11 humidity and temperature sensor

* Pin 4: A light sensor (photoresistor)

* Pin 18: A button to be used to poweroff the Pi safely.

The pi can be wired like this:

Running the script

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

You can run the script using:

```

sudo python wotkitdemo.py

```

Running at boot

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

We provide a bash script named ``runwotkitdemo.sh'' you can use to deploy at boot. First create a log file named 'cronlog', in our case we have created it at ```/home/pi/wotkitdemo/logs```. 

Then you can add the following line to your crontab via ```sudo crontab -e```, which will boot the

```

@reboot sudo sh /home/pi/wotkitdemo/runwotkitdemo.sh > /home/pi/wotkitdemo/logs/cronlog 2>&1 &

```
