Hi Alain!
Thank you please take care of the family first. I will not even have a sensor to test until after the first of the new year. Probably a MCP3202 A to D and an
18f1320 although I am open to any and all suggestions. I can test the sensor in a tub of water much like part of a wooden barrel with an arm that spins the sensor in the water and there is a stop watch with a switch to start and stop the stop watch for the time part. I have 6 different speed for the motor that drives the arm that spins just above the water with just the sensor pick up tube in the water. I hope you and your family had a great holiday and that everyone will have a happy and prosperous new year!

Best, Ed
