POWER AND MONITOR 16 HALL EFFECT SENSORS

Can the 16 x 12 bit PWM shield be used to provide 5v power to 16 hall effect sensors and then scan the signal pin sequentially of each sensor?

No. The PCA9685 is a 'write only' device. An MCP23017 can probably do what you need:

We have a few prototyping shields that would accommodate that chip: https://www.adafruit.com/category/358
