Figured Id throw this out there and see what others think...Has anyone ever had to install the EZB Ultrasonic sensor (or any other sensor) far away from the EZB? for my current bot project I am working on, I need to place the sensor far away from the EZB, like 40 inches away, due to the current size of the robot. I know the short 3pin servo wire that comes with the sensor works fine, and the signal looks good on a scope.
Next I tried a longer wire, some 36 inches. It still worked, and still gives readings on the EZB software (the latest and greatest version). What I did noice on the scope was a lil bit of noise on the echo/trigger line, about 1.6V yet it still produces a typical 5V square wave, but the accuracy of the readings is a lil off.
Just wondered if anyone ever tried a longer cable and maybe had to add some filtering to the power or signal lines of the sensor to clean things up.
The robot is over 5 feet tall. this one sensor is to be located at its tracked base, and am planning to put the EZB in the head.
