Embedded System

Location Finder Unit  Modules used for the project. ARM7(LPC2148) microcontroller used as the processor GPS module with UART(3.3v TTL) interface  GSM/GPRS modem module with RS232 serial interface Power Supply(5v for ARM board GPS,7v for GSM modem) Software devoloped with Rowly Cross Studio 2.0   IDE (GNU C compiler) compiled output is in hex format,this target software is flashed to processor with Philips Flash utility. Functions:- Show the location details (Latitude,Longitude) in LCD. Simply make a ring to this unit,it will give the informations through SMS- Example -If you are using in School Bus parents can make a ring (no call charge) and get the position of School Bus. Latitude,Longitude Speed Direction Name of the location Stored information(coustomized message for individual calling numbers) Facility for storing the information for current position- Name of location To include in category list like ATM,Petrol Pump,Police Station,Hotels et...

Global Positioning System Started to develop GPS/GSM project I purchased one GPS unit and GSM/GPRS modem for this project. ARM7 (LPC2148) processor (Blue Board) board is using for this project. GPS data receiving side is ok, position data is getting in NMEA  format(ascii text). In the first stage , I use this data for  maping in Google earth. GPS receiver data out is in UART (TTL3.3v) communication. Data received from GPS via UART conected to ARM through UART0. Processed data fed to the PC via BlueBoard's UART1. But my laptop having only USB. This problem solved by RS232 to USB convertor. GPS data to be linked to the Google Earth by any bridge software (earthbridge). Now the position showing in google earth according to gps data. In google Earth we can save the track,map,trip etc in XML formal and can be share with others by email. National Marine Electronics Association NMEA  has developed a specification that defines the interface between various pieces...

Water level monitoring used in smarthome is my own design.It is based on the movement of floating magnet.Two reed switch used for upper and lower sensing.When the floating magnet reach near the reed switch,the "NO" contact will close.

Now my project is finished state and it is going to install. System features: 1.Door monitoring 2.Light control(porch light,rear light) depends on stored schedule 3.Over head water tank level monitoring and pump operation 4.Refrigerator power saving depends on stored schedule 5.Alarm facility for different times. Schedules and other settings can be done through front pannel keys PC interface also provided for scheduling and other settings.

Now I am preparing for establishing an embedded webserver
