PProject roject IIdeadea The goal of this project to monitor and control a
chicken farm by SMS from far place , two part is used:
one is serial port with mobile & temperature sensor & infra red sensor that sense the change in degree in the farm & any unfamiliar movement ,this part called (sensing part) .
Two is simply mobile you can receive messages from first part and send command messages to it this part called( controlling part).

1- our project aims to allow owners to monitor and control their farms or houses devices from far places.
2- allow owners to control their farms or houses by cheap cost.
WWhere here WWe e CCan an UUse se TThis his PProjectroject??
1- We can use this project in any place need to be controlled and monitored , such as your home, company ,farms , …….
2- In our case we choose the chicken farm to control and monitor it.
WWhat hat WWe e MMust ust KKnownow ??
To get started doing our project several points are to be determined:
1 -GSM network 2 -Type of mobile useable
3 -Sensors behavior a- temperature sensor
b- infrared sensor
AAT T TTestest

TTo o PPerform erform TTestestTo use HyperTerminal to send SMS to your mobile phone using AT commands we follow the procedure below:
1.Connect your mobile phone to a computer by using a serial cable.
2. Run HyperTerminal by selecting Start -> Programs -> Accessories -> Communications -> HyperTerminal.
3. In the Connection Description dialog box enter a name and choose an icon you like for the connection. Then click the OK button.
4. In the Connect To dialog box, choose the COM port that your mobile phone is connecting to in the Connect using combo box. Then click the OK button.
5. The Properties dialog box comes out. Enter the correct port settings for your mobile phone. Then click the OK button.
6. Then go to file > properties>setting >ASCII setup> echo typed characters locally then click the ok button.

The LM335 are precision temperature sensors which can be calibrated. They operate as a 2-terminal Zener and the breakdown voltage is directly proportional
to the absolute temperature at 10mV/K .
WWhy hy LM335LM335 ? ?
1. Easy to calibrate.2. Simple to implement.3. Has large current range from 450μA to 5 mA.4. Have a typical error of less than 1Cº over a
100Cº temperature range.

At 20 c° the output voltage = 2.5 V.At 30 c° the output voltage = 3.5 V.

PProblemsroblems1. It is difficult to choose the kind of
temperature sensor & to find it is correct cct that we will use it to calibrate it .
2. 2. The connection between microcontroller (PIC) and mobile phone .
3. Programming the microcontroller (PIC).
