MCU connecting two model 3144 switch hall sensors, the distance between the two sensors, known objects through A sensor to count (record object through A number of sensors), again after B sensor also count, by counting the time difference between the two t to calculate the speed of moving objects, and determine the direction of the moving object, two sensors count data, object movement speed, direction, these data should be displayed in the LCD1602 screen, and can realize the function of the code!

This method for low speed measurement are ok, you a fast, the error is big
