This project aim is to design automated air craft cabin parameters monitoring and alerting system. The proposed system continuously monitors the parameters like temperature, pressure, humidity inside the flight along with the door status and alerts through buzzer, if anything went wrong.   The controlling device of the whole system is a Microcontroller. Different sensors like temperature, pressure, door status, humidity are interfaced to Microcontroller. The Microcontroller is programmed to monitor the parameters continuously and alert if any of the parameter is out of range to the given parameter value. The parameter threshold level can be dynamically varied. The alerting is done through a buzzer. Continuous display of the parameters on LCD is available.  To perform this intelligent task, the Microcontrollers are loaded with intelligent programs written using embedded ‘C’ language.      

The main objectives of the project are:  

1. Designing of air craft cabin parameters monitoring and alerting system.
2. Dynamic parameter threshold level setting provision.
3. Alerting, in case abnormal parameter values.

        The major building blocks of the project are:  

1. Regulated Power Supply.
2. PIC Microcontroller.
3. Temperature sensor.
4. Humidity sensor.
5. Pressure sensor.
6. LCD with driver.
7. Buzzer with driver.
8. Parameter Threshold setter.
9. Door status sensor.
10. Crystal
11. LED indicators.

      Software’s used:  

1. PIC-C compiler for Embedded C programming.
2. PIC kit 2 programmer for dumping code into Micro controller.
3. Express SCH for Circuit design.
