About this project

A.S.C.H. (Automatic safe chicken house)

We are Ruben Smid and Thomas De Zaeyer. We follow the fifth year industrial engineering V.T.I. in Veurne. We have realized the project A.S.C.H. to give people with chickens an easier life.. we automate the chicken coop First we make sure that the chickens come in in the evening and are not attacked by predators. Then, we ensure that the chickens get get food and drink automatically and sent a shortage of food and drink. It is also intended to check the freshness of the eggs by keeping track of when the eggs have been laid.

We program or systems with Arduino because it’s easy to use.

We use a daylight sensor to open the door when its day and close the door in the evening.

For the eggs-system, its simple a pushbutton and a motion sensor. When the motion sensor don’t see a chicken and the pushbutton is pushed in, there wil be blink a led.

We have also a system that detect the fresh air in the coop. when the gas sensor detect to match bad air, on your phone there will be a signal.

The food system is just a motor that we don’t have a the moment and that will rotate a mill that give the chickens just enough food for the day.

/*

Arduino UART Demo Sketch. This Sketch is made for an Genuino 101 IoT board with a Grove
UART WiFi module based on the popular ESP8266 IoT SoC to communicate to the AllThingsTalk
IoT developer cloud.
The Grove UART WiFi module has firmware installed which includes the ATT_IOT library. It
communicates through Serial1 of the Genuino 101 board.

Version 1.0 dd 26/12/2015

This sketch is an example sketch to deploy the Grove Button (101020003) to the
AllThingsTalk IoT developer cloud.


### Instructions
1. Setup the Arduino hardware
  - Use an Arduino Genuino 101 IoT board
  - Connect the Arduino Grove shield
  - Connect USB cable to your computer
  - Connect a Grove Button to pin D2 of the Arduino shield
  - Grove UART wifi to pin UART (D0,D1)
2. Add 'ATT_IOT_UART' library to your Arduino Environment
     More info can be found at http://arduino.cc/en/Guide/Libraries
3. Fill in the missing strings (deviceId, clientId and clientKey) in the keys.h file
4. Optionally, change sensor names, labels as appropiate
5. Upload the sketch

Note: for use of extra actuators, extend the callback function at the end of the sketch
