AIM: To save the power which is wasted when the receiver is not placed on the transmitter.
Description: My idea is to save the power consumption of the wireless transmitter module when ever the device is idle. we can achieve this by placing a simple proximity sensor at the center of the coil.so that we the module knows when the receiver is placed on the top of transmitter.
The transmitter is switched on only when there is a receiver is placed on the top of it. In idle time it will be in switch off mode. This can save a large amount of power used by the transmitter.
The above picture describes my idea.
