I'm new to this electronic side, I'm working on this new academic project where we can connect the key chain with a mobile application using bluetooth. whenever the keychain was out of the range it should send us notification.
I'm looking for a Bluetooth module and a small battery source to power the module.
What type of module is better suited for this project and what type of power source is apt for the module. What are things should I consider before starting this project?
select bluetooth according: Data rate, mode, transmit distance.
select battery according: bluetooth voltage, bluetooth power (current) requirement, expected power up time.
do an internet search, read some datasheets to find out what best suits your needs.
unclear: where does the key chain come from? what does "out of range" mean? where does the bluetoth send to?
We have planned to integrate the Bluetooth module on keychain which will be paired with mobile application. whenever the keychain and the mobile application were separated, the App should send us notification stating "you forget your keychain".
Given the scenario, the only objective is to pair the keychain with mobile application whenever it is in range say 10 - 20 meters, if the keychain and the mobile go past beyond this range the app will send a notification.
Is it possible to develop communication with mobile application using only Bluetooth module or do we need some microcontroller to control the Bluetooth module for this project?
