Question: A manufacturing plant uses two tanks to store certain liquid chemicals that are required in a manufacturing process. Each tank has a sensor that detects

A manufacturing plant uses two tanks to store certain liquid chemicals that are required in a manufacturing process. Each tank has a sensor that detects when the chemical level drops to 25% of full. The sensors produce a HIGH level of 5V when the tanks are more than one-quarter full. When the volume of chemical in a tank drops to one-quarter full, or less, the sensor puts out a LOW level of 0V. It is required that a single green light-emitting diode (LED) on an indicator panel shows when both tanks are less than one-quarter full.
