I want to turn on/off my GPS(SKM53) using transistor based circuit as it consumes too much current 45mAh so i want to save my battery.
I need help in solving this problem keeping in mind the following limitations :
1. My battery voltage is 3.4v
2. GPS current requirement is...
Can you provide me the schematics for this purpose.

i think load current detection will be more accurate and simpler solution in my case. here is one circuit i found :
check this circuit guys and guide me...
Thank you for replying. Yes well transformer and hall effect sensor can be used but transformer is bulky device and more over there are 8 bulbs and i want to know to status of each bulb separately n this means if i use transformer or hall effect sensor then i need 8 transformers/sensors for this...
I have an AC bulb operating at 220v 50Hz , i want a circuit that determines automatically either the bulb is fused or not. I need 5v and 0v logic for this purpose as i need this feedback for the micro-controller.
I have considered several solutions for this purpose :
1. When the bulb...
