River water level
« on: May 29, 2019, 12:40:31 PM »

WATER HEIGHT ?   ---   I know this isn't quite robotic, however from what you do discuss here I hope maybe you can give me some ideas and suggestions.  Looking at using an ultrasonic system  (WINGONEER DC 5V Waterproof Ultrasonic Distance Sensor system  ) and mounting the sensor on a post overlooking the river.  I will use the waterproof sensor.  Take the echo return time signal and use it to start and stop a counter.  (Digiten 4 digit LED counter panel meter.  )   Looking at the LTC6900 to create about a 5.6 KC  time base for measuring the distance in feet.  ---   A couple questions:  Can I extend the cable between the control module and the sensor to 250 feet?  If so can I use multi conductor cable, or would the sensor need to have coax?  What kind of stability is reasonable to expect using these parts and overall method?     Any thoughts and/or other ideas?  How about a better way?    Comments ?  ?  Thanks
