Hi everyone,

I want to implement a analog circuit which can sense the change in voltage at the sensor output to switch my mosfet.
My application is to power on my MCU when there is a change in voltage(nothing but change in weight)

Can anybody help me out

Thanks in advance

Regards,
Kranthi.
 

hi,
A simple option would be to use a LM393 dual comparator IC.

Post some details of your sensor.
