Hi, I have a electronics problem (surprise surprise)
This is my problem
Current system consists of a sensor which outputs a variable frequency (square wave say between 0Hz and 5000Hz, 0-5V signal)
This frequency is read by a computer, which does stuff based on what the current frequency is. Nothing new here
What I want to do is introduce a second sensor.
The idea is that each sensor does half the job. However with 2 sensors my max frequency is doubled.
The problem is in sending the frequency signal to the computer (which cannot know that anything is different) which is equal to the sum of both sensor frequencies. While the sensor frequencies ideally will be fairly similar, there is no guarantee.
for example, if sensor 1 reads 10Hz and sensor 2 reads 20Hz, I want the computer to read 30Hz.
Any ideas? I am hoping there is a fairly simple solution, however I am unable to come up with one myself.
Much appreciated,
K
