Today we will talk about :Today we will talk about :
1. Project idea and over view.
2. Where we can use it.
3. What we need to know.
4. AT Commands Test .
5. Project flow chart.
6. Temperature and IR Sensors.
7. Problems.

3. PProjectroject 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.
WWherehere WWee CCanan UUsese TThishis 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.

6. WWhathat WWee MMustust 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

To 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.

10. 3. In the Connection
Description dialog box
enter a name and choose
an icon you like for the
connection. Then click the
OK button.

11. 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.

12. 5. The Properties
dialog box comes
out. Enter the correct
port settings for your
mobile phone. Then
click the OK button.

13. 6. Then go to file >

23. PPrecisionrecision TTemperatureemperature SSensorensor
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.

24. WWhyhy 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.

25. TTemperatureemperature SSensorensor ccctct
The practical calibrationThe practical calibration
At 20 c° the output voltage = 2.5 V.
At 30 c° the output voltage = 3.5 V.

27. PProblemsroblems
1. 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).
