The main aim of this project is to develop data logging system using Bluetooth. Say for e.g.: think we are designing the Blue tooth based remote reading of the house energy meter. In this project the user can access and download the data from his computer remotely using the blue tooth enabled mobile. In the receiver side there will be hard ware with microcontroller, Bluetooth Transmitter and Receiver.
When the user request the data, then at the transmitter side it will sense the request and check the security conditions, if every thing is correct then it will down load the data from PC and send the data through blue tooth medium. In our project the PCB is designed by using Express PCB & the circuit is designed by using Proteus software.
Bluetooth remote data logger is similar to the wired RS232 data logger. But the only difference is that this uses the Bluetooth medium to get the data from the remote devices. Say for e.g.: think we are designing the Bluetooth based remote reading of the house energy meter. Above picture shows the Transmitter diagram of for this project.
The energy meters will have a Bluetooth transmitter and a Blue tooth receiver. And a micro-controller will be connected to read the energy meter readings and it is stored in the memory.
